Opinion of the Court by
BURNS, C.J.
Jason McElroy (McElroy or Defendant) appeals from the June 7, 2002 Judgment of the First Circuit Court1 convicting him of Sexual Assault in the Third Degree, Hawaii [381]*381Revised Statutes (HRS) § 707-732(l)(a) (1993)2, and sentencing him to probation for five years, subject to special terms and conditions. We vacate the June 7, 2002 Judgment and remand the case to the circuit court for a new trial.
BACKGROUND
A University of Hawaii (UH) dormitory apartment (the apartment) was occupied by the following four females: C.E., S.W., E.M., and J.F. The apartment had two bedrooms, a kitchen, and a living room. One of the bedrooms was occupied by C.E. and S.W., and the other was occupied by E.M. and J.F.
On the evening of October 31, 2001, C.E., S.W., and E.M., along with approximately ten other friends from the UH and elsewhere, met at the apartment. Three members of the group included the following three members of the United States Navy: Corey Blackwell (Blackwell), Lucas Tetrault (Tet-rault), and McElroy. This was the first time C.E. had ever met McElroy. The group left the apartment and headed into Wai-klkL Although C.E. admits to having “[t]hree or so” beers before leaving the apartment, she denies drinking alcohol in Wai-klki.
C.E. testified that she, her boyfriend (Boyfriend), and S.W. headed back to the apartment around 1:00 a.m. C.E. recalled that she was tired and dehydrated upon arrival, so she and Boyfriend went to sleep. She remembers falling asleep in her bed with Boyfriend between 1:00 a.m. and 2:00 a.m. C.E. testified that she went to bed wearing only a bra and her underwear. Boyfriend testified that after C.E. and S.W. fell asleep, he went home.
E.M. testified that she, Blackwell, Tetrault, and McElroy arrived back at the apartment between 2:00 a.m. and 3:00 a.m. Once in the apartment, McElroy went into C.E. and S.W.’s bedroom and asked S.W. if he could share one of the bedroom’s two beds with her. S.W. agreed and McElroy “squeez[ed]” into her bed. According to S.W., “at our apartment ... people stay over and we always share a bed together, like friends and stuff, and nothing ever happens.”
S.W. testified that soon after McElroy got into the bed he told her “I’m not going to let you sleep, and then ... he touched me by my waist on the right side ... and then he grabbed my, uh, breast.” S.W. testified that she did not at any time give McElroy permission to touch her. S.W. immediately responded by grabbing her pillow and blanket, moving to the couch in the living room, and going to sleep there.
C.E. testified that after she fell asleep in her bed, she “was kind of waking up, kind of half dreaming, half asleep to someone touching me around my vagina. And I thought that it was [Boyfriend], so I didn’t open my eyes because he had been there. He was the last person who had been in my bed.” She then testified that “this person was licking around my vagina and stuck his fingers in my vagina and then licked—started to lick around my anus and then stuck his fingers in my anus. And that’s when I opened my eyes to see who it was.” C.E. testified that she thought it would be Boyfriend when she opened her eyes, but when she saw that it was McElroy, “I was appalled. I was shocked. I was disgusted. I was angry. I was—-I couldn’t believe it. It was the last thing I would have ever expected.” She remembered that she “asked him who the fuck he was, and I then I [sic] told him to get the fuck out of my room.” C.E. testified that she did not give McElroy permission to touch her in any way, and the entire contact could have gone on for ten (10) or fifteen (15) minutes. After being told by C.E. to get out of her room, McElroy left. McElroy did not attempt to restrain C.E. in the room, and he did not have to be forced out of her room.
S.W. testified that she called campus security and at approximately 3:26 a.m., the police arrived.
McElroy testified that the police took him to the police station, handcuffed him, and placed plastic bags over his hands to pre[382]*382serve any evidence. After sitting in a holding area for several hours, the following occurred:
Q The detective asked if you wanted to make a statement?
A Yes.
Q And you made a statement?
A Yes.
Q You didn’t ask to talk to a lawyer first?
A No.
Q You didn’t just keep your mouth shut?
A No.
Q Did you want to tell them what had happened?
A Yes.
Q After making your statement to the police, to ... Detective Kellett, what happened?
A After that they sent me to a cell. They just basically sent me back to my cell. ‘Cause they made me sleep it off. I had to sleep it off first because I was still drunk when I went there. Then after I talked to him, they sent me to a cell.
On November 6, 2001, a grand jury indicted McElroy on five separate counts of sexual assault. Count I charged McElroy with knowingly subjecting C.E. “to an act of sexual penetration by compulsion, by placing his mouth on her vagina, thereby committing the' offense of Sexual Assault in the Second Degree.”
Count II charged McElroy with knowingly subjecting C.E. “to an act of sexual penetration by compulsion, by inserting his finger into her vagina, thereby committing the offense of Sexual Assault in the Second Degree.”
Count III charged McElroy with knowingly subjecting C.E. “to an act of sexual penetration by compulsion, by placing his mouth on her anus, thereby committing the offense of Sexual Assault in the Second Degree.”
Count IV charged McElroy with knowingly subjecting C.E. “to an act of sexual penetration by compulsion, by inserting his finger into her anus, thereby committing the offense of Sexual Assault in the Second Degree.” Count V charged McElroy with knowingly subjecting S.W. “to sexual contact by compulsion, by placing his hand on her breast, thereby committing the offense of Sexual Assault in the Fourth Degree.”
On November 2, 2001, the Office of the Prosecuting Attorney recommended bail for McElroy in the aggregate amount of $25,000.00. The Bail Form submitted to the court by Deputy Prosecuting Attorney Scott Bell (the Prosecutor) states, in relevant part, that
[C.E.] is a 20 year old college student at UH who was asleep in her dorm room when she was sexually assaulted by [McEl-roy], a sailor in the U.S. Navy. [C.E.] is from out of state. [C.E.] does not know [McElroy]. [McElroy] assaulted victim by placing his mouth on [C.E.’s] vagina and anus, and by inserting his finger into her vagina and anus. [McElroy] has a record in Illinois.
The Prosecutor did not identify the specifics of McElroy’s “record in Illinois.”
On November 26, 2001, McElroy filed a Motion for Supervised Release and/or Bail Reduction. On December 18, 2001, the response of the State of Hawai'i Department of Public Safety was filed. It revealed that, “[according to the National Crime Information Center, [McElroy] was arrested in Chicago, Illinois, on April 21, 1999, for Possession of Cannabis, and on December 14, 1998, for Possession of Controlled Substance. There was no conviction information reported.” 3
[383]*383On March 8, 2002, McElroy filed Defendant’s Motion in Limine # 1 asking for various orders including the following:
4. [McElroy] requests an Order excluding and precluding from use at trial the following evidence:
(a) Any testimonial or documentary evidence or reference by any State witness relating to any prior allegations of criminal acts by [McElroy]; and
(b) Testimonial or documentary evidence relating to any other “bad acts” involving [McElroy], or matters which should nevertheless be excluded as irrelevant under [Hawaii Rules of Evidence (HRE) ] 402, or as unfairly prejudicial under HRE 403, including but not limited to:
i) A statement allegedly made by State’s witness, Lucas Tetrault, to HPD Officer Dru Akagi, that “... he knows how “Mac” [sic] can be. He can be aggressive towards women.”
On March 11, 2002, the day oefore the trial commenced, the State had no objection to requests 4(a) and (b), and the court granted those requests.4
During his trial, on direct examination by his counsel, McElroy testified, in relevant part, as follows:
Q [McElroy], after you graduated from high school, what did you do?
A I joined the Navy.
Q Why did you join the Navy?
A Because to make my family proud. And I was doing bad and I wanted to change and stuff like that.
Q So after high school, you thought that it would be a positive thing for you to join the Navy?
A Yes.
Q And what did that give you a chance to do?
A Go to college and see the world and just learn something new.
Q Is that one of your goals, to eventually go to college?
A Yes.
Q And the Navy would be able to help you with that?
A Yes.
McElroy testified that when S.W. got up out of bed he also got up “ ‘[c]ause when she opened the door and left out [sic], I smelled the food, and so then I got out right behind [384]*384her and walked right out too. And then I went in the kitchen with Cor[e]y where he was cooking.” After that he went back to S.W.’s bedroom and laid down on S.W.’s bed. McElroy testified that the following then occurred:
And I was laying down and the alcohol was messing with my head because I had been up sitting down all day. And then when I finally lay still, the alcohol had my head spinning. So I was like twisting and turning in the bed. And then when I finally stopped, [C.E.] was like, “Hey, you, come over here. And then I told her who I was. And she was like, Hey, you, come over here. And then that’s when I went over there.”
McElroy then testified that he went over to C.E. and she hugged him and gave him a kiss on the cheeks and on the lips. McElroy then “pulled her panties like to her knees, and then she wiggled out of them.” McElroy performed oral sex on her for about eight (8) to twelve (12) minutes. After having oral sex with C.E., McElroy went up to kiss her and “she kissed me again. This time it was like a longer kiss. And then after that, it was like hocus-pocus or whatever you want to call it. And she was just like, [g]et off me, you mother fucker, and stuff like that.” McElroy said he “jumped back”, walked out of the room, and told Tetrault what happened. McElroy went back in the room to apologize to C.E., but she again told him to get out. McElroy admitted that he did not ask C.E. for permission to have oral sex with her.
On cross-examination, the Prosecutor asked McElroy about his background:
Q You also told us that you joined the' Navy to change; is that correct?
A Yes.
Q Change from what?
A Well, when I was back home, I was doing bad. Well, I was hanging with the wrong people—drugs and gang-banging and stuff like that. And I got tired of doing that[.]
Immediately, McElroy’s defense counsel asked to approach the bench, where the following dialogue took place:
[DEFENSE COUNSEL]: Well, Judge, I have to move for a mistrial. I didn’t anticipate that answer from [McElroy]. And I believe [the Prosecutor] violated the motion in limine regarding bad acts. It was in response to a question posed.
[PROSECUTOR]: Your Honor, I was completely unaware of anything. On direct, the defense asked, why did you join the Navy, and he said to change. So I simply just followed that up. I didn’t know of any bad acts. I just followed it up with what [Defense Counsel] asked on direct. I was completely unaware of any bad acts. I don’t have a rap for defendant. I don’t know anything about him. But the defense during his opening questions to him asked him why he joined the Navy.
THE COURT: I’m going to instruct the jury to disregard it. I’m going to take the ■motion for mistrial under advisement.5
[PROSECUTOR]: And I’ll move along.
THE COURT: You better.
(Footnote added.)
The bench conference concluded and the court instructed the jury as follows: “[T]he Court is going to strike the defendant’s last answer. Whatever the defendant did prior to his joining the Navy is not relevant to any issue before this jury. So you will disregard that. It shouldn’t have been before you at all.”
McElroy continued to testify, stating that he did not know C.E. and Boyfriend were girlfriend and boyfriend. McElroy also said that, until S.W. told him, he was unaware that C.E. thought he was Boyfriend.
After the completion of McElroy’s testimony, the case was sent to the jury. During its deliberations, the jury sent three communications to the court. The first communication was received on Friday, March 15, 2002 at 1:54 p.m. and said, “We cannot agree. Where do we go from here? Re: Element Number Two.” The court’s response was, “Please continue your deliberations.”
The second communication from the jury asked:
[385]*385Please clarify: Does the legal definition of “compulsion” mean the same in offense [sic] of Sexual Assault in the Second degree as well as Sexual assault in the Third degree? Also, does consent have to be given before physical contact. We’d appreciate some direction on these points so we can arrive at a just decision in a timely manner.
The court answered:
As to your first question, the definition of “compulsion” on page 21 of the jury instructions 6 applies to both Sexual Assault in the Second Degree and Sexual Assault in the Third Degree.
As to your second question, this is something you must determine based upon the jury instructions you already have.
The third communication from the jury stated, “We have reached a unanimous decision on Counts I in the Third Degree and Count V.” The court replied by asking, “Have you reached a unanimous verdict as to each of the five counts?” The jury answered, “No.” The court then asked, “Would further deliba'ation of any length be reasonably likely to result in a unanimous verdict as to any of Counts II, III, or IV?” The jury again answered, “No.”
The jury was called in to read its verdicts on Counts I and V. Before the verdicts were read, the court declared a mistrial on Counts II, III, and IV because the jury was unable to reach a unanimous verdict in those matters. As to Count I, the jury found McElroy guilty “of the included offense of Sexual Assault in the Third Degree.” As to Count V, the jury found McElroy not guilty.
McElroy filed a notice of appeal on July 1, 2002. The appeal was assigned to this court on August 6, 2003.
POINT OF ERROR
McElroy’s sole point of error on appeal is that the court reversibly erred when it denied his motion for mistrial after the prosecution “engaged in misconduct when it elicited ‘prior bad acts’ of [McElroy]”.
STANDARD OF REVIEW
A. The Difference Between a Prosecutorial Mistake/Error and Prosecutorial Misconduct
The California Court of Appeals for the 5th District has stated that:
It is settled that a mere mistake relative to the admissibility of proferred evidence is not misconduct in the absence of a showing that the prosecutor was not acting in good faith. The term “misconduct,” when applied to an act of an attorney, implies a dishonest act or an attempt to persuade the court or jury by use of deceptive or reprehensible methods.
Similarly, the Pennsylvania Supreme Court has held that no basis exists for the claim of prosecutorial misconduct where the improper questioning was not intended to inflame the passions and prejudices of the jury to the extent that the defendant was deprived of a fair trial.
State v. Palabay, 9 Haw.App. 414, 429-30, 844 P.2d 1, 9 (App.1992) (citations omitted).
The primary reason a distinction must be made between a prosecutorial mistake/error and prosecutorial misconduct is Rule 8.4 of the Hawai'i Rules of Professional Conduct (2004). It states as follows:
Misconduct.
It is professional misconduct for a lawyer to:
(a) violate or attempt to violate the rules of professional conduct, knowingly assist or induce another to do so, or do so through the acts of another;
(b) commit a criminal act that reflects adversely on the lawyer’s honesty, trustworthiness, or fitness as a lawyer in other respects;
(c) engage in conduct involving dishonesty, fraud, deceit, or misrepresentation;
(d) fail to cooperate during the course of an ethics investigation or disciplinary proceedings;
[386]*386(e) state or imply an ability to influence improperly a government agency or official; or
(f) knowingly assist a judge or judicial officer in conduct that is a violation of applicable rules of judicial conduct or other law.
Prosecutorial misconduct is a violation of Rule 8.4 of the Hawai'i Rules of Professional Conduct (2004). Prosecutorial mistake/error is not a violation of that rule.7
B.The Standard of Review Applicable to a Prosecutorial Mistake/Error and Prosecutorial Misconduct
Although the following precedents speak only of “prosecutorial misconduct”, they apply to both prosecutorial misconduct and a prosecutorial mistake/error.
“Prosecutorial misconduct warrants a new trial or the setting aside of a guilty verdict only where the actions of the prosecutor have caused prejudice to the defendant’s right to a fair trial.” State v. Mara, 98 Hawai'i 1, 16, 41 P.3d 157, 172 (2002) (quoting State v. Clark, 83 Hawai'i 289, 304, 926 P.2d 194, 209 (1996)). Prosecutorial misconduct is “reviewed under the harmless beyond a reasonable doubt standard, which requires an examination of the record and a determination of whether there is a reasonable possibility that the error complained of might have contributed to the conviction.” State v. St Clair, 101 Hawai'i 280, 286, 67 P.3d 779, 785 (2003) (citations and internal quotation marks omitted). The prosecution bears the burden of showing that the misconduct was harmless beyond a reasonable doubt. State v. Smith, 91 Hawai'i 450, 461, 984 P.2d 1276, 1287 (App.1999). Factors to consider are: (1) the nature of the prosecutorial misconduct; (2) the promptness or lack of a curative instruction; and (3) the strength or weakness of the evidence against the defendant. State v. Wakisaka, 102 Hawai'i 504, 513, 78 P.3d 317, 326 (2003) (citation omitted). Under the Hawai'i Constitution, “reproseeution is barred where, in the face of egregious prose-cutorial misconduct, it cannot be said beyond a reasonable doubt that the defendant received a fair trial.” St. Clair, 101 Hawai'i at 287, 67 P.3d at 785 (citation omitted).
C.The Standard of Review Applicable to the Erroneous Admission of Evidence of Prior Crimes
“The standard of review applied to the erroneous admission of evidence of prior crimes is whether ‘the error was harmless beyond a reasonable doubt.’ ” State v. Kutzen, 1 Haw.App. 406, 414, 620 P.2d 258, 263 (1980) (quoting State v. Pulawa, 62 Haw. 209, 220, 614 P.2d 373, 379 (1980)).
D.Denial of a Motion for Mistrial
“The denial of a motion for mistrial is within the sound discretion of the trial court and will not be upset absent a clear abuse of discretion.” State v. Rogan, 91 Hawai'i 405, 411, 984 P.2d 1231, 1237 (1999) (citations omitted). An abuse of discretion occurs when the trial court “clearly exceeds the bounds of reason and disregards rules or principles of law or practice to the substantial detriment of a party litigant.” Id. (citations omitted).
DISCUSSION
A. The Relevant Prohibitions
The relevant suppression order prohibited “[tjestimonial or documentary evidence relating to any other ‘bad acts’ involving [McEl-roy], or matters which should nevertheless be excluded as irrelevant under HRE 402, or as unfairly prejudicial under HRE 403[.]”
Even in the absence of a relevant suppression order, a prosecutor errs when he or she presents evidence of the defendant’s prior criminal activity, Pulawa, 62 Haw. at 220, 614 P.2d at 379, except in situations where evidence of the defendant’s prior criminal activity is admissible pursuant to HRE Rules 403 and 404.
[387]*387B.Defendant Did Not Violate Either of the Relevant Prohibitions
The following question and answer did not violate the relevant prohibitions:
Q Why did you join the Navy?
A Because to make my family proud. And I was doing bad and I wanted to change and stuff like that.
C. The Prosecutor Violated Both Relevant Prohibitions
The prosecutor violated both relevant prohibitions when he introduced the following evidence:
Q You also told us that you joined the Navy to change; is that correct?
A Yes.
Q Change from what?
A Well, when I was back home, I was doing bad. Well, I was hanging with the wrong people—drugs and gang-banging and stuff like that. And I got tired of doing that[.]
D. Defendant’s Answer Was Not a Damaging Statement Volunteered by the Defendant
Damaging statements volunteered by the defendant generally are not grounds for declaring a mistrial. See People v. Barker, 161 Mich.App. 296, 305-306, 409 N.W.2d 813, 817 (1987); cf. People v. Kirkwood, 17 Ill.2d 23, 31, 160 N.E.2d 766, 771 (1959) (defendant in no position to complain about volunteered statement because there was nothing in the record to show the prosecutor was attempting to introduce prejudicial evidence).
The State contends that MeElroy’s “response was volunteered [so] the State should not be held responsible for it.” We conclude that MeElroy’s answer was not a “volunteered statement” because a defendant’s relevant answer in reasonable response to a question is not a “volunteered statement.]” In this case, MeElroy’s answer was a relevant answer in reasonable response to the Prosecutor’s question. The difference between a relevant answer in reasonable response to a question and a volunteered statement is emphasized in State v. Corella, which states:
Lastly, Defendant claims that two responses by Complainant in cross-examination were non-responsive and, in the aggregate, prejudicial. In the first response, Complainant stated she knew that Defendant had been violent in the past. The judge struck this remark from the record. Soon after the first response, Complainant stated that Defendant had “fondled” other women in public. The judge refused to strike this comment.
[[Image here]]
The first response was made in the following context:
Q. [ (Defense attorney) ] [Defendant] did not strike you in any way; is that a fair statement?
A. [ (Complainant) ] That is a fair statement. [Defendant]—
Q. Just [sic] asked you if he had stricken you, if he had attempted or actually hit you in any way up to this point?
A. No.
Q. Okay.
A. I am aware of his violence in the past.
[Defense attorney]: I move that that be stricken from the record and the jury be instructed to disregard that comment.
THE COURT: So ordered. The jury will disregard the last remark.
Defendant submits that the unfair prejudice resulting from Complainant’s unsolicited reference to Defendant’s alleged prior bad acts was not cured by the trial court’s prompt instruction. The Supreme Court of Hawai'i has held that “any harm or prejudice resulting to the defendant [from a remark by a witness for the prosecution] can be cured by the court’s instructions to the jury. In such cases it will be presumed that the jury adhered to the court’s instructions.” Even so, there are instances where a “deliberate and unresponsive injection by [a] prosecution [witness] of irrelevant references to prior ... [bad acts] may generate insurmountable prejudice to the cause of an accused.”
[[Image here]]
[388]*388The colloquy that gave rise to the second response was as follows:
Q. [Complainant], didn’t, you know— let’s be honest with—honest with each other. After everything you have testified that happened, your response is—you recall the dialogue with [Defendant], he turned past your place, he goes down few [sic] miles, he goes up the dirt road, he shuts the ignition, you know, shuts the lights off, he slips across the bench seat, tries to kiss you, and you don’t know what—what’s about to happen or what he wants?
A. I couldn’t believe that [Fianeé’s] best friend and somebody that I had been acquainted with would do anything to me that [Defendant] had done.
Q. Well, you did not believe that may be [sic] he might try to have sex with you after he kept putting his hands on your leg, you told us, repeatedly between Keaau [Kea'au] and Pahoa? You kept saying he kept repeatedly putting his hands on—on your thigh, didn’t he?
A. Sir—
Q. What does that tell you, [Complainant]? He repeatedly puts his hand on thigh—on your thigh, you’re repeatedly pushing his hand away, and he’s repeatedly putting his hands back on your thigh. [Complainant], what do you think it is he wants to do there?
A. Sir, [Defendant] has fondled several women—
[DEFENSE ATTORNEY]: I object.
A. —in public.
[DEFENSE ATTORNEY]: I object, and move that that be stricken from the evidence. I asked what she thought was happening. That’s a gratuitous comment of the—
[DEPUTY PROSECUTING ATTORNEY]: I also—Your Honor, counsel opened this. He—
THE COURT: I think she [sic] answering you as best way [sic] she can. Overruled.
A trial court’s admission of testimony is reviewed for abuse of discretion. The proper remedy for a non-responsive or improper answer to a proper question is to have the answer stricken. As with the prior considered remark, Complainant’s answer here was not specifically responsive to defense counsel’s question.
79 Hawai'i 255, 264-65, 900 P.2d 1322, 1331-32 (App.1995) (brackets in original); see also State v. Kuba, 68 Haw. 184, 189, 706 P.2d 1305, 1309 (1985) (“Officer Main ... asked if she had been drinking, which she readily admitted. She told him she had a drink earlier that night and then volunteered she had been cited for three traffic violations a few minutes earlier.”); In Re Doe, 76 Hawai'i 85, 90 n. 7, 869 P.2d 1304, 1309 n. 7 (1994) (“No questions were posed of any witness soliciting any characterization of the Minor’s ‘tone,’ and no testimony was volunteered in this regard.”)
E. Prosecutorial Mistake/Error, Not Prosecutorial Misconduct
We conclude that a prosecutorial error/mistake, not prosecutorial misconduct, occurred when the Prosecutor, during his cross-examination of McElroy, asked, “[c]hange from what?”
In support of its argument that the Prosecutor’s question was not prosecutorial misconduct or prosecutorial error/mistake, the State repeats what the Prosecutor told the trial court:
Your Honor, I was completely unaware of anything. On direct, the defense asked, why did you join the Navy, and he said to change. So I simply just followed that up. I didn’t know of any bad acts. I just followed it up with what [Defense Counsel] asked on direct. I was completely unaware of any bad acts. I don’t have a rap for defendant. I don’t know anything about him....
The Prosecutor’s during-trial statements to the court that he “was completely unaware of any bad acts” and did not “have a rap for defendant” are contradicted by the fact that the Prosecutor, in his pre-trial comments to the court regarding the issue of bail for McElroy, told the court that “[McElroy] has a record in Illinois.” However, the Prosecutor made these during-trial statements to the [389]*389court after the jury heard McElroy’s prejudicial testimony.
The State also asserts that “[tjhere was nothing improper or suggestive about [the Prosecutor’s] question, it did not naturally call for such a response nor did it infer such a response.” We disagree. McElroy had already testified that “I was doing bad and I wanted to change[.]” This testimony did not violate either of the two relevant prohibitions. Evidence of “doing bad” is not “testimonial or documentary evidence relating to any other ‘bad acts’ involving [McElroy], or matters which should nevertheless be excluded as irrelevant under HRE 402, or as unfairly prejudicial under HRE 403,” nor is it “evidence of the defendant’s prior criminal activity[J”
In light of McElroy’s testimony that he joined the Navy to change from “doing bad”, the following questions asked by the prosecutor and the evidence introduced in response to them violated both of the relevant prohibitions.
Q You also told us that you joined the Navy to change; is that correct?
A Yes.
Q Change from what?
A Well, when I was back home, I was doing bad. Well, I was hanging with the wrong people—drugs and gang-banging and stuff like that. And I got tired of doing that—
This conclusion is based on the facts that this examination asked McElroy to state the specifics of his “doing bad” and those specifics included McElroy’s prior criminal activity and thereby created the strong likelihood of introducing evidence in violation of the suppression order. This questioning had no more than the following two purposes: (a) repeating McElroy’s “doing bad” testimony; and/or (b) disclosing evidence that would violate the suppression order. If the purpose was (a), the questioning was irrelevant, dupli-cative, and superfluous. If the purpose was (b), it violated the suppression order and the rule of evidence stated in State v. Pulawa, supra.
In People v. Harges, the Appellate Court of Illinois stated, in relevant part:
We are in accord with the defendant’s contention that he was deprived of a fair trial by prejudicial tactics of the prosecutor during the course of the trial. The prosecutor asked the defendant, on cross-examination, about the events that occurred subsequent to his arrest, and in particular about what transpired in the Fillmore Police Station:
Q. What did you observe at the Fillmore Police Station, did you see anything on the wall?
A. Some signs in regard to the law, and it said something about your rights to legal counsel.
Q. Have you ever seen Fillmore Station before?
A. I have, do you mean before I was arrested?
Q. At any other time?
Mr. Bronstein: Objection to counsel’s speech.
The Court: Sustained.
Mr. Davidson (prosecutor): What is he objecting to?
The Court: He is objecting to him asking has he seen Fillmore Police Station before.
Mr. Davidson: So you sustained the objection.
The Court: That is correct.
The State, in its brief, insists that the question asked of the defendant—“Have you ever seen Fillmore Station before?”—, when it stands alone, is totally vague and ambiguous; the defendant’s claim that this question suggested to the jury defendant’s prior arrest record is pure conjecture; and moreover, that the Court sustained counsel’s objection to this question, and therefore no error was committed. The evidence in this case was of such a character that the prosecutor’s question relating to a prior arrest of the defendant was clearly improper; this question represented an obvious attempt by the prosecution to bring to the attention of the jury the fact that the defendant had been to the Fillmore Station on a prior arrest. We can see no other purpose for this inquiry. It had [390]*390no bearing on the question of guilt. ' It was otherwise irrelevant to and unconnected with any of the testimony previously given by the defendant on direct examination. Conduct such as that exhibited by the prosecutor in the instant case has been condemned on many occasions. The error is not cured by the court sustaining an objection. People v. Black, 317 Ill. 603, 614, 148 N.E. 281. As the Supreme Court stated in People v. Decker, 310 Ill. 234, 141 N.E. 710, “There is no question more damaging to a defendant with a jury than one that suggests or intimates that he is a cirmi-nal [sic] or has been charged with criminal offenses.” (P. 243, 141 N.E. p. 714.) Such conduct is clearly reversible error.
87 Ill.App.2d 376, 379-81, 231 N.E.2d 650, 652-53 (1st Dist.1967).
Viewed in context, however, the cross-examination that led to the violation of the court’s suppression order was the Prosecutor’s mistake/error, not “a dishonest act or an attempt to persuade the court or jury by use of deceptive or reprehensible methods.” Palabay, 9 Haw.App. at 429, 844 P.2d at 9.
F. The Erroneously Admitted Evidence Was Not Harmless Beyond a Reasonable Doubt
As noted above, a prosecutorial mistake/error in the presentation of evidence is “reviewed under the harmless beyond a reasonable doubt standard, which requires an examination of the record and a determination of whether there is a reasonable possibility that the error complained of might have contributed to the conviction.” St. Clair, 101 Hawai'i at 286, 67 P.3d at 785 (citations and internal quotation marks omitted). Factors to consider are: (1) the nature of the prose-cutorial mistake/error; (2) the promptness or lack of a curative instruction; and (3) the strength or weakness of the evidence against the defendant. Wakisaka, 102 Hawai'i at 513, 78 P.3d at 326.
1. Nature of the Prosecutorial Mistake/Error
It is commonly recognized across the nation that evidence that the defendant participated in “gang-banging”8 is often unfairly prejudicial, since juries frequently associate gangs with criminal activity and improperly convict based on inferences to the defendant’s character. See 39 A.L.R.4th 775 (1985); see also State v. Kauhi, 86 Hawai'i 195, 206, 948 P.2d 1036, 1047 (1997). Evidence of defendant’s participation in “gang-banging” will therefore only be admissible when its probative value outweighs the risk of unfair prejudice. See HRE 403. Considering that the present case is about a single incident of alleged sexual assault, the mention of McElroy’s involvement in “drugs and gang-banging and stuff like that” was irrelevant, and more unfairly prejudicial than it was probative. HRE 403.
2. The Promptness of a Curative Instruction
Ordinarily it may be presumed that a jury will abide by the court’s instruction to disregard anything that has been improperly placed before it. The error is generally considered cured by the instruction. But an instruction not to consider incompetent testimony does not always cure the error. When the testimony is prejudicial [391]*391to the opposing party’s cause, the presumption prevails only if there is a reasonable certainty that the impression upon the jury could be or was dispelled by the court’s admonition. The error is not cured when it is likely that the adverse effect of the improper testimony might not be eradicated by the instruction.
Young v. Price, 48 Haw. 22, 27, 895 P.2d 365, 368 (1964) (citations omitted). This rule applies with equal force when the testimony is prejudicial to the testifying party’s cause.
In the case at hand, the trial judge instructed the jury immediately after McEl-roy’s counsel moved for a mistrial. The court stated: “[T]he Court is going to strike the defendant’s last answer. Whatever the defendant did prior to his joining the Navy is not relevant to any issue before this jury. So you will disregard that. It shouldn’t have been before you at all.” This instruction weighs in favor of the State. It was prompt, and it addressed the lack of relevance McEl-roy’s statement had to the ease before the jury. Nevertheless, we are not reasonably certain that the negative impact McElroy’s testimony of his prior involvement in “drugs and gang-banging and stuff like that” was erased by the court’s admonition. It is very possible that the court’s instruction did not eradicate the adverse effect of MeElroy’s testimony.
3. The Strength or Weakness of the Evidence
Since the principal issue at McElroy’s trial was whether C.E. consented to having sex with him, this case is similar to the facts in Rogan, 91 Hawai'i at 415, 984 P.2d at 1241, because it revolves around the credibility of the only two parties in the bedroom at the time the alleged sexual assault took place— C.E. and McElroy.9 This case is also similar to Rogan because there “were no independent eyewitnesses” to the alleged assault and the Prosecutor’s case against McElroy “depended heavily on [C.E.’s] testimony.” Id.
Initially, the jury was unable to attain a unanimous verdict on any of the five counts against McElroy. In fact, the jury was only able to agree to one guilty verdict—Count I in the lesser included third degree. For the remaining charges, the jury found McElroy not guilty on Count V, and was unable to reach a verdict on Counts II, III, and IV.
Given that the case was based on C.E.’s version of events versus MeElroy’s version, “we cannot say that the evidence of criminal conduct against [McElroy] was overwhelming.” Rogan, 91 Hawai'i at 415, 984 P.2d at 1241.
Based on the above analysis, we conclude that the Prosecutor’s mistake/error leading to MeElroy’s statement about drugs and gangs was not harmless beyond a reasonable doubt. A reasonable possibility exists that the prejudicial testimony that resulted from the Prosecutor’s prosecutorial mistake/error could have contributed to McElroy’s conviction and, therefore, denied McElroy’s right to a fair and impartial trial. St. Clair, 101 Hawai'i at 286, 67 P.3d at 785. Therefore, we vacate his conviction.
G. Denial of Defendant’s Motion for Mistrial
In light of our decision, it is not necessary for us to decide whether the trial court abused its discretion in denying McElroy’s motion for a mistrial.
CONCLUSION
Accordingly, we vacate the June 7, 2002 Judgment Guilty Conviction and Probation Sentence in which McElroy was (1) convicted and found guilty of Sexual Assault in the Third Degree, in violation of Hawaii Revised Statutes § 707-732(l)(a), and (2) sentenced to five years’ probation subject to special terms and conditions. We remand this case to the circuit court for a new trial consistent with the holdings in this opinion.
