OPINION OF THE COURT
Chief Judge Kaye.
In
People v Darden
(34 NY2d 177, 181), the Court held that when information obtained from a confidential informant is necessary to establish probable cause, it would be “fair and wise” for the People to “be required to make the informer available for interrogation before the Judge” in an ex parte hearing. The question before us today is whether
Darden
established a requirement, or merely a procedure to be allowed in the discretion of the trial court. We reiterate that a
Darden
hearing is a requirement rather than a matter of discretion.
This case arises out of the December 1, 1993 shootings of Milton Clarke (an auxiliary police officer) and Chester Martin. Clarke died as a result of the shooting; Martin survived but lost a leg. On March 18, 1994, a confidential informant — a witness in an unrelated homicide — saw a reward poster in a New York City Police Department station house concerning the shootings. The informant told Detective Neenan that a person he knew as “Tony” had confessed to him that he had committed the crimes. The informant gave a description of “Tony” and told Detective Neenan other details about the shootings. In addition, the informant stated that “Tony” had admitted shooting John Thomas in an unrelated incident on July 4, 1993.
One week later, Thomas informed the police that the person who shot him on July 4, 1993 was named Johnson Edwards. The police also received an anonymous phone call in which the caller gave a description of Edwards. On April 28, 1994, Detective Burke received a call from another unnamed informant stating Edwards’ whereabouts. Based on that tip, the police apprehended defendant. After defendant had been taken into custody, the police showed Thomas a photograph of defendant, and Thomas confirmed that defendant was the person who had shot him on July 4, 1993. Subsequently, Chester Martin and two other witnesses to the December 1, 1993 shooting identified defendant in a lineup as the shooter.
Under Bronx County Indictment Number 3299/94, defendant was charged with second-degree murder, attempted murder, assault and several weapons offenses for the shootings of Clarke and Martin. A hearing was held on defendant’s motion to suppress the lineup identifications, at which Detective Neenan testified about the investigation and arrest of defendant, as well as the lineup. On cross-examination, defense counsel asked the detective for the name of the March 18, 1994 informant. The prosecutor objected. Defense counsel then asked, in the alternative, that the court examine the informant in camera to determine “whether this individual exists and what information he had.” The court denied defense counsel’s requests, stating that it did not need to examine the informant, or know his name, in order to make its probable cause determination.
Following the hearing, the court issued a written decision denying defendant’s motion to suppress, holding that the arrest was supported by probable cause. The court noted that the police had the right to rely on the information supplied by the confidential informant, because the informant provided a sufficient basis for his knowledge, had given reliable information in the past and furnished details consistent with information already known to the police. The court found additionally that the lineup was not suggestive. A jury convicted defendant of second-degree murder and attempted murder.
The Appellate Division affirmed, holding that the trial
court “properly exercised its discretion” in denying defendant’s motion for an in camera examination of the confidential informant (268 AD2d 288, 289). The court stated that an in camera hearing was not necessary because the evidence adduced at the suppression hearing “satisfied the
Aguilar-Spinelli
test,” and defendant “made no showing to warrant an in camera examination”
(id.).
On appeal to this Court, defendant argues that the trial court erred by denying his request for an in camera examination of the confidential informant. We agree.
The Informer’s Privilege at Suppression Hearings
The use of confidential informants to establish probable cause presents a difficult issue for the courts. As a general rule, hearsay is admissible at a suppression hearing
(see,
CPL 710.60 [4]). A police witness at a suppression hearing may establish probable cause by personal knowledge, as well as by information supplied by fellow officers or private citizens
(see, People v Washington,
87 NY2d 945, 947;
People v Parris,
83 NY2d 342, 346). The People are not required “to produce any particular witness, provided they sustain their burden of coming forward with evidence showing that there was probable cause for the arrest”
(People v Parris, supra,
at 346;
see also, People v Chipp,
75 NY2d 327, 337-339 [defendant does not have an absolute right to call the complaining witness to testify at a
Wade
hearing],
cert denied
498 US 833). The People may even rely on hearsay evidence provided by an anonymous tipster, “so long as the requirements of the
Aguilar-Spinelli
test are met”
(People v Parris, supra).
As a counterbalancing principle, the defendant has a right to cross-examine the People’s witnesses at the suppression hearing
(see, People v Williamson,
79 NY2d 799, 800-801 [trial court committed reversible error by curtailing cross-examination of witness at suppression hearing]). Thus, in the ordinary case where a police officer has obtained evidence from a third person providing probable cause, the defendant has the opportunity to question the officer about the third person’s identity, relationship to the crime, basis of knowledge, past relationship to the police and criminal history. The defendant is thus able to raise any appropriate question about the officer’s testimony to the suppression court.
In the case of a confidential informant, however, the defendant’s ability to test the officer’s claim of probable cause is circumscribed. Since it is often important to maintain the secrecy of the informant’s identity, especially at the early stages of a criminal proceeding, trial courts have the discretion to prohibit a defendant from eliciting the informant’s name or any other information that could reveal the informant’s identity
(see, People v Castro,
29 NY2d 324, 326 [finding it “unnecessary” to disclose informant’s name at suppression hearing where other evidence established informant’s reliability];
People v Coffey,
12 NY2d 443, 450-453 [upholding trial court’s decision not to disclose informant’s name where informant’s existence and statements were verified by sworn testimony from Assistant District Attorney],
cert denied
376 US 916;
McCray v Illinois,
386 US 300, 311-314 [due process does not require disclosure of an informant’s identity at a suppression hearing]). Thus, the defendant would be “thwarted” in efforts to test the officer’s credibility

(34 NY2d 177, 181), the Court held that when information obtained from a confidential informant is necessary to establish probable cause, it would be “fair and wise” for the People to “be required to make the informer available for interrogation before the Judge” in an ex parte hearing.

The use of confidential informants to establish probable cause presents a difficult issue for the courts. As a general rule, hearsay is admissible at a suppression hearing
(see,
CPL 710.60 [4]). A police witness at a suppression hearing may establish probable cause by personal knowledge, as well as by information supplied by fellow officers or private citizens
(see, People v Washington,

People v Parris,
83 NY2d 342, 346). The People are not required “to produce any particular witness, provided they sustain their burden of coming forward with evidence showing that there was probable cause for the arrest”
(People v Parris, supra,
at 346;
see also, People v Chipp,
75 NY2d 327, 337-339 [defendant does not have an absolute right to call the complaining witness to testify at a
Wade
hearing],
cert denied
498 US 833). The People may even rely on hearsay evidence provided by an anonymous tipster, “so long as the requirements of the
Aguilar-Spinelli
test are met”
(People v Parris, supra).
As a counterbalancing principle, the defendant has a right to cross-examine the People’s witnesses at the suppression hearing
(see, People v Williamson,
79 NY2d 799, 800-801 [trial court committed reversible error by curtailing cross-examination of witness at suppression hearing]). Thus, in the ordinary case where a police officer has obtained evidence from a third person providing probable cause, the defendant has the opportunity to question the officer about the third person’s identity, relationship to the crime, basis of knowledge, past relationship to the police and criminal history. The defendant is thus able to raise any appropriate question about the officer’s testimony to the suppression court.
In the case of a confidential informant, however, the defendant’s ability to test the officer’s claim of probable cause is circumscribed. Since it is often important to maintain the secrecy of the informant’s identity, especially at the early stages of a criminal proceeding, trial courts have the discretion to prohibit a defendant from eliciting the informant’s name or any other information that could reveal the informant’s identity
(see, People v Castro,
29 NY2d 324, 326 [finding it “unnecessary” to disclose informant’s name at suppression hearing where other evidence established informant’s reliability];
People v Coffey,
12 NY2d 443, 450-453 [upholding trial court’s decision not to disclose informant’s name where informant’s existence and statements were verified by sworn testimony from Assistant District Attorney],
cert denied
376 US 916;
McCray v Illinois,
386 US 300, 311-314 [due process does not require disclosure of an informant’s identity at a suppression hearing]). Thus, the defendant would be “thwarted” in efforts to test the officer’s credibility
(see, 2
Wayne R. LaFave, Search and Seizure § 3.3 [g], at 188 [3d ed]).
Responding to these concerns, in 1974 this Court established a procedure to verify the testifying officer’s credibility while keeping the informant’s identity secret. The Court held that, where “there is insufficient evidence to establish probable cause apart from the testimony of the arresting officer as to communications received from an informer,” it would be “fair and wise” for the People to “be required to make the informer available for interrogation before the Judge”
(People v Darden, supra,
34 NY2d, at 181). In order to protect the informer’s confidentiality, the prosecutor may be present at the hearing, but defendant and defense counsel may not. Defense counsel, however, may submit, in writing, suggested questions for the Judge to ask the informant, and the transcript of the in camera hearing must be placed under seal and made available to appellate courts should the case be appealed. Further, a “summary report” of the hearing should be made available to defense counsel and the People, regarding “the existence of the informer” and the “communications made by the informer to the police”
(id.).
By contrast, at trial, “where the defendant’s guilt or innocence is at issue, disclosure of the informant’s identity should not be resolved in an ex parte proceeding”
(People v Liberatore,
79 NY2d 208, 215).
The Trial Court’s Obligation under
Darden
In the present case, the trial court prohibited defendant from cross-examining Detective Neenan about the confidential
informant’s identity. The court, however, declined to follow the
Darden
procedure, holding that it could rely on the information provided by the informant without examining him in camera. That ruling was error.
At the outset, we reject the People’s contention that probable cause could be established without the informant’s statements, which would render a
Darden
hearing unnecessary. The People argue before us that John Thomas’ identification of defendant as the person who shot him provided an independent basis for his arrest. The People, however, did not raise that theory before the trial court; they argued only that Thomas’ identification of defendant from a single photograph was “confirmatory” of the information provided by the confidential informant and other unnamed sources. The People’s current argument is therefore unpreserved. In any event, Thomas did not identify defendant until
after
he was arrested; indeed, the identification was made from defendant’s arrest photograph.
We likewise reject the People’s argument that the trial court’s refusal to follow the
Darden
procedure was a proper exercise of discretion. Where, as here, the informant’s testimony is necessary to establish probable cause, the court must grant the defendant’s request for a
Darden
hearing. To be sure, there are exceptions to the
Darden
rule. Informants need not be produced, for example, if they cannot be located despite the People’s diligent efforts
(see, People v Fulton,
58 NY2d 914, 916), or if they refuse to appear because they fear personal injury
(see, People v Carpenito,
80 NY2d 65, 68). In such cases, the People may instead “establish the existence of confidential informants through extrinsic evidence” after demonstrating that “the informant is legitimately unavailable”
(id.).
Moreover, informants who previously testified before the Magistrate who issued a warrant need not be produced for a
Darden
hearing, since their existence and statements have already been verified
(see, People v Serrano,
93 NY2d 73, 76-77).
The existence of these exceptions reinforces our holding that
Darden
did in fact establish a rule. If, as the People contend,
Darden
had established only a discretionary procedure, there would have been no need for exceptions. Further, our precedents speak of
Darden
hearings as required rather than discretionary. In
People v Serrano
(93 NY2d,
supra,
at 77), for example, this Court stated that a
Darden
hearing “is
required
‘where there is insufficient evidence to establish probable cause apart from the testimony of the arresting officer as to com
munications received from an informer’ ” (quoting
People v Darden, supra,
34 NY2d, at 181 [emphasis added]). The Court explained that an in camera hearing is necessary to allay any concern that the informant is “wholly imaginary” and his statements to the police “fabricated”
(People v Serrano, supra,
at 77).
Similarly, in
People v Adrion
(82 NY2d 628, 634), we held that a trial court’s order to produce an informant for an in camera examination is mandatory, and the prosecutor must comply on pain of suppression. The Court described the
Darden
hearing as a requirement, stating that once the defendant has challenged the informant’s existence or identity, “the People are required to produce the police informant for an in camera inquiry unless they can demonstrate that the informant is unavailable and cannot be produced through the exercise of due diligence”
(id.).
Further, as we stated in
Serrano
and
Adrion,
a
Darden
rule is necessary in order to fulfill the underlying purpose of Darden: insuring that the confidential informant both exists and gave the police information sufficient to establish probable cause, while protecting the informant’s identity. The surest way to accomplish this task is to produce the informant for an in camera examination. In addition, this rule gives clear guidance to lower courts and guarantees that “the protections of the Fourth Amendment have not been circumvented” (2 LaFave, Search and Seizure,
supra,
§ 3.3 [g], at 203).
People v Huggins
(36 NY2d 827, 828), on which the People rely, is not to the contrary. In
Huggins,
the Court held that the trial court’s failure to order in camera examination of a
confidential informant was not an abuse of discretion, noting that
Darden
provides “guidelines to assist the courts in exercising their discretionary powers * * * to hold in camera inquiries”
(id.).
Significantly, the suppression hearing in
Huggins
took place before
Darden
was decided. Cognizant of that fact, the
Huggins
Court could not say that the trial court — which did not have the benefit of
Darden
— abused its discretion as a matter of law, and did not address whether
Darden
established a mandatory procedure for subsequent cases. Thus,
Huggins
is inapplicable here. Furthermore, any language in
Huggins
suggesting a discretionary standard is contradicted by our strong endorsement in
Adrion
of a mandatory procedure and by our subsequent statement in
Serrano
that
Darden
creates a requirement.
Nor is a
Darden
hearing unnecessary if the police officer’s testimony satisfies the
Aguilar-Spinelli
test. That test provides that a tip from a hearsay informant (which may include an anonymous informant) may not be used unless the source of his knowledge is revealed and the informant is of known reliability
(see, People v DiFalco,
80 NY2d 693, 696-697;
People v Elwell,
50 NY2d 231, 236;
see generally, Spinelli v United States,
393 US 410;
Aguilar v Texas,
378 US 108).
The People contend that since this test applies even to an anonymous informant, it should apply to a confidential informant as well, and where the officer’s testimony establishes both the informant’s reliability and basis of knowledge, the information may be used to establish probable cause without a
Darden
hearing. In
Adrion,
however, this Court rejected that very argument, holding that the concerns are different when a confidential informant is involved, since the reason for the
Darden
rule is to verify the informant’s
existence
— not merely to establish the reliability of a tip
(see, People v Adrion, supra,
at 634-636). Further, while the defendant has free reign to cross-examine the officer about any relevant subject where an anonymous tip is used, the defendant cannot cross-examine the officer about any matter that may reveal the identity of a confidential informant. Therefore, in the case of a confidential informant, an in camera inquiry is necessary to properly test the officer’s credibility. Moreover, unlike anonymous tipsters, it is possible
to bring confidential informants before the Judge to verify their existence and statements.
Finally, contrary to the Appellate Division, defendant was not required to make any threshold showing in order to be entitled to a
Darden
hearing
(see, Matter of Pierre H.,
260 AD2d 320, 320-321;
People v Ferron,
248 AD2d 962, 963,
lv denied
92 NY2d 879). Obviously, it would be difficult, if not impossible, for a defendant to present evidence that a confidential informant did not exist or was unreliable. It was error for the Appellate Division to place a burden on defendant that he could not reasonably have been expected to meet
(see,
2 LaFave, Search and Seizure,
supra,
§ 4.4 [d], at 505 [discussing a defendant’s duty to make a “threshold showing” to challenge a warrant: where the defendant cannot discover the identity of the informer, “the defendant should not be deemed to have failed in his ‘threshold showing’ merely because he has no information as to whether the informant lied to the officer-affiant * * * or the officer-affiant lied to the magistrate”]).
Defendant, therefore, is entitled to remittal to Supreme Court for a
Darden
hearing, at which the court shall conduct an in camera examination of the confidential informant. Alternatively, if the People demonstrate that one of the exceptions to the
Darden
rule applies, they may establish the informant’s existence and reliability through other evidence.
Defendant’s remaining contention is without merit.
Accordingly, the order of the Appellate Division, insofar as appealed from, should be modified by remitting to Supreme Court for further proceedings in accordance with this Opinion and, as so modified, affirmed. If, on remittal, Supreme Court determines that probable cause to arrest was lacking, then the judgment of conviction under Indictment Number 3299/94 should be vacated and the motion to suppress granted. If Supreme Court determines that probable cause to arrest existed, then the judgment should be amended to reflect that result.
Judges Smith, Levine, Ciparick, Wesley and Rosenblatt concur.
Order, insofar as appealed from, modified, etc.
