OPINION
CANTU, Justice.
Appellant was convicted of attempted capital murder. Trial was to a jury with punishment being assessed at seventy-five (75) years’ confinement in the Texas Department of Corrections.
The sufficiency of the evidence is not questioned. Only three grounds of error are raised on appeal, all addressing trial court error in abusing its discretion. A brief recitation of the facts is necessary in order to address the error complained of.
[311]*311The instant case arose out of an incident occurring on September 8, 1978, when a small red-orange car bearing California plates was observed parked on Preston Street in Pleasanton, in Atascosa County. The car was seen parked at different times at various locations, arousing the suspicions of an insurance agent who observed two black men in the automobile. Later, the same automobile was seen parked on Preston Street with the license plates having been removed.
Pleasanton Police Chief Bill Dean and Police Sergeant Lester F. Fuller were dispatched to the scene to investigate. As they exited their patrol car and approached the small car from behind, they saw appellant’s head appear from the driver’s side window and they observed a pistol being aimed at them. The officers were wearing full dress uniforms and were carrying service revolvers. As the officers retreated with their hands in the air, in response to verbal orders given by appellant, Fuller was shot in the chest at very close range. A high speed chase ensued with appellant driving and his brother firing shots at the pursuing officers. Some thirty miles from Pleasanton, in Live Oak County, at a roadblock, appellant brought the car to a stop and both were apprehended and placed under arrest.
Appellant and his brother, Elston Donnell Gammage, were each charged by an Atasco-sa County grand jury in two separate indictments with attempted capital murder, and in another indictment with resisting arrest or search by use of a deadly weapon, all arising out of the same criminal escapade. The trial court ordered the cases severed as to the offense charged but mandated a joint trial of the two co-defendants for the offenses. Trial on the instant case addressed the first incident, giving rise to attempted capital murder in the criminal escapade.
The trial was transferred to Karnes County upon the sustaining of a joint motion for change of venue. At the close of the State’s case the jury returned verdicts acquitting the co-defendant and convicting appellant of attempted capital murder, as charged in the indictment.
In his first ground of error appellant alleges that the trial court erred in trying him while handcuffed before the jury. Trial on the merits began with jury selection on January 8,1979, but at a pretrial hearing on January 4, 1979, the State had obtained a hearing on its motion to have appellant and his brother tried while under physical restraints. The motion was heard in Karnes County where appellant was being housed when not in the Nueces County jail. By this time, appellant and his brother had been away from the Atascosa and Karnes County jails almost twelve weeks.
In support of its motion the State offered the testimony of Sheriff Edwin Jalufka of Karnes County, who testified that he preferred to have both co-defendants under physical restraints throughout the trial because they were more dangerous than any other prisoners he has ever had. He based his opinion of dangerousness on the facts giving rise to the case being tried. He admittedly knew nothing about the criminal history of either but concluded that each had a bad temper because they had complained about the food being served at the Karnes County jail. The sheriff testified that he was not aware of any threats having been made by either appellant or his brother while they were being detained at the Karnes County jail. However, he had been told of an alleged escape attempt involving the co-defendants while they were being held at the Atascosa County jail.
The sheriff indicated that he planned to have four or five deputies, in addition to himself, assigned to the joint trial for security. While Sheriff Jalufka had no personal knowledge of any of the misdeeds attributed to appellant and his brother, he unequivocally testified that neither co-defendant had misbehaved while in his custody. While the testimony presented to the trial court consisted primarily of hearsay evidence several times removed, the trial court had heard other evidence relevant to the motion at some of the earlier pretrial hearings.
[312]*312On October 13,1978, a motion filed by the State seeking transfer of appellant and his brother to another jail was heard by the trial court. At that hearing Tommy Williams, the Sheriff of Atascosa County, testified that his jail was undergoing repair work and was an unsatisfactory security risk in handling prisoners charged with the type of offenses lodged against appellant and his brother. According to the sheriff only one person was assigned to work the jail at night as a dispatcher on the first floor, and he could not provide surveillance on the third floor of the jail where appellant, his brother, and seven other prisoners were housed in a ten-man cell.
The sheriff testified that two or three days before the hearing to transfer, a newly dug hole had been discovered in the wall of the holding tank in which appellant and the other eight prisoners were being held. No evidence was presented bearing on who the perpetrators of the escape attempt were. The sheriff presumed that some or all of the prisoners were responsible.
No threats about escape were ever made by appellant or his brother in the presence of the sheriff. However, the sheriff related that his dispatcher had overheard threats of escape made by prisoners on the third floor. According to the sheriff, informants had told him that appellant and his brother had indicated their intention to escape.1
A few days after appellant and his brother were first lodged in the Atascosa County jail a surprise inspection of the jail had revealed several homemade knives and at least one factory-made knife. The sheriff admitted that the jail population was regularly turned over and that no opportunity existed for inspecting the premises prior to placing new prisoners in the cells. The record does not reveal when the knives were obtained.
Although the third floor of the jail contained prisoners charged with murder, aggravated robbery, aggravated assault and other violent crimes, only appellant, his brother, and an extradition detainee were singled out for treatment as dangerous prisoners requiring transfer to a more secure jail. The three were subsequently transferred to the Nueces County jail. Thereafter, appellant and his brother were regularly transferred back and forth from the Nueces County jail to the Karnes County jail as needed for pretrial hearings. During the various lengthy pretrial hearings held in Atascosa County and in Karnes County, neither appellant nor his brother ever acted in any manner evidencing a need for restraints.
At one of the hearings the sheriff complained about appellant’s refusing to be in court wearing leg irons.2 On another occasion the sheriff complained that appellant and his brother had become uncooperative when one of his deputies failed to wake them up in time to dress and prepare for court appearance. The sheriff admitted to the court that the fault was his in not awakening appellant until 8:30 a. m. for a 9:00 o’clock court appearance.
The record reflects that appellant and his brother periodically attended hearings from shortly after their arrest on September 8, 1978, until January 8, 1979, when trial on the merits began, without ever causing any disruption of the court proceedings or in any manner presenting a security problem.
Counsel for appellant strenuously objected to having appellant tried under restraints. The objections were reurged at various stages of the trial and the trial court eventually agreed to note counsel’s continuing objection.
The apprehensive trial court declined the State’s demand for leg irons but required both defendants to be tried wearing hand[313]*313cuffs. The trial court stipulated that the restraints would be visible to the jury and acknowledged that they would be prejudicial.
The record reflects that the Sheriff of Atascosa County was deeply concerned with the condition of his jail which was being repaired by having its windows sealed and bricked in. The description of the jail indicates the structure to be old and inadequate. A shortage of manpower is also evident from his testimony.
On the other hand, the Sheriff of Karnes County simply overreacted to the concern exhibited by the Sheriff of Atascosa County without independently ascertaining whether a problem existed some twelve weeks later.
The cautious trial court was outwardly concerned about the need for physical restraints and attempted to mitigate the prejudice by declining to require leg irons and restraining belts. In addition, he allowed both defendants to dress in civilian clothing while in court. The decision to require restraints was not immediately arrived at, the trial court instead taking the matter under advisement. However, once the decision was made the trial court committed itself to full implementation of the order.
The State argues that appellant was not unduly prejudiced because only handcuffs were used during the trial, he was nicely dressed in street clothes and no undue emphasis was placed on the handcuffs. Additionally, during oral argument before this court, the State intimated that appellant is in no position to claim prejudice because the co-defendant, also tried in handcuffs, was acquitted by the jury, thereby providing proof positive that the restraints produced no negative influences upon the jury’s deliberations.
We disagree for reasons herein enumerated.
Among the most precious rights afforded an accused is the right to be tried before an impartial jury with the presumption of innocence fully intact and free of prejudice. Intimately interwoven into the foregoing rights is the proposition that no accused should ever be subjected to physical restraints of any kind in the courtroom while in the jury’s presence, unless there is a showing of “exceptional circumstances” or a “manifest need” for such restraints. Gray v. State, 99 Tex.Crim.R. 305, 268 S.W. 941 (1924); Rainey v. State, 20 Tex.App. 455 (1886).
The removal of physical restraints prior to a defendant’s appearing before the jury is also desirable to assure that “every defendant is ... brought before the court with the appearance, dignity and self-respect of a free and innocent man.” Kennedy v. Cardwell, 487 F.2d 101, 104 (6th Cir. 1973).
In recognizing that an accused has a right to be free from physical restraints while being tried, the courts have referred to several detrimental effects which result from the use of such restraints.
Initially, the courts have recognized that physical restraints on an accused tend to prejudice the jury against the accused and suggest to the jury that the trial judge, by ordering or permitting the use of such restraints, has thereby expressed the opinion that the accused is a dangerous person and is not to be trusted. Illinois v. Allen, 397 U.S. 337, 90 S.Ct. 1057, 25 L.Ed.2d 353 (1970); Mouton v. State, 155 Tex.Crim.R. 450, 235 S.W.2d 645 (1950); Gray v. State, supra; Zunago v. State, 63 Tex.Crim.R. 58, 138 S.W. 713 (1911); Rainey v. State, supra, at 472 citing State v. Kring, 64 Mo. 591. Secondly, the courts have recognized that the use of physical restraints on the accused during the trial tends to interfere with his thought processes, the use of his faculties, and his ability to communicate with counsel. Illinois v. Allen, 397 U.S., at 344, 90 S.Ct., at 1061, 25 L.Ed.2d, at 359; Rainey v. State, supra. Finally, the courts have recognized that the use of physical restraints on an accused during the trial constitutes an affront to the dignity of judicial proceeding. Illinois v. Allen, 397 U.S., at 344, 90 S.Ct., at 1061, 25 L.Ed.2d, at 359.
In recognizing that “exceptional circumstances” or “manifest need” can override an [314]*314accused’s right to be tried free from physical restraints, the courts have alluded to those situations in which an accused has expressed his intention to escape,3 has made threats of physical violence,4 has resisted being brought to court,5 has repeatedly interrupted the court proceedings,6 has attempted to leave the courtroom,7 has assaulted persons in court,8 has persisted in unruly conduct while in court,9 or has engaged in or threatened other nonconforming conduct.10
But the threats or the acts must be real and not merely speculative. Before a trial court is authorized in ordering the physical restraint of an accused on trial before a jury, he should conduct a hearing outside the presence of the jury and include his reasons for taking extreme measures as a part of the record. Kennedy v. Cardwell, 487 F.2d 101 (6th Cir. 1973), cert. denied, 416 U.S. 959, 94 S.Ct. 1976, 40 L.Ed.2d 310 (1974); Woodards v. Cardwell, 430 F.2d 978 (6th Cir. 1970), cert. denied, 401 U.S. 911, 91 S.Ct. 874, 27 L.Ed.2d 809 (1971); Freeman v. State, 556 S.W.2d 287 (Tex.Cr.App.1977); Moore v. State, 535 S.W.2d 357 (Tex.Crim.App.1976); Thompson v. State, 514 S.W.2d 275 (Tex.Cr.App.1974); Walthall v. State, 505 S.W.2d 898 (Tex.Crim.App.1974); Gray v. State, supra; People v. Duran, 16 Cal.3d 282, 127 Cal.Rptr. 618, 545 P.2d 1322 (1976); See also American Bar Association Standards Relating to the Administration of Criminal Justice, in § 5.3(b) of “The Function of the Trial Judge” and in § 4.1(c) of “Trial by Jury.”
The decision to use physical restraints must be made by the trial judge on a case-by-case basis and the use of such restraints will necessitate reversal only where the decision constitutes an abuse of discretion. Illinois v. Allen, supra; Morris [315]*315v. State, 382 S.W.2d 259 (Tex.Cr.App.1964); State v. Reid, 114 Ariz. 16, 559 P.2d 136 (1976) cert. denied, 431 U.S. 921, 97 S.Ct. 2191, 53 L.Ed.2d 234 (1977).
In addressing the problem of physically restraining an accused on trial before a jury, the United States Supreme Court in Illinois v. Allen, supra, focused on those situations arising in the courtroom giving impetus to a trial judge’s use of discretion in resolving the crisis. In doing so it stated:
It is essential to the proper administration of criminal justice that dignity, order and decorum be the hallmark of all court proceedings in our country. The flagrant disregard in the courtroom of elementary standards of proper conduct should not and cannot be tolerated. We believe trial judges confronted with disruptive contumacious, stubbornly defiant defendants must be given sufficient discretion to meet the circumstances of each case.
397 U.S., at 343, 90 S.Ct., at 1061, 25 L.Ed.2d, at 359.

... [N]o person should be tried while shackled and gagged except as a last resort. Not only is it possible that the sight of shackles and gags might have a significant effect on the jury’s feelings about the defendant, but the use of this technique is itself something of an affront to the very dignity and decorum of judicial proceedings that the judge is seeking to uphold.
397 U.S., at 344, 90 S.Ct., at 1061, 25 L.Ed.2d, at 359.
The true danger of subjecting an accused to trial under physical restraint in the presence of a jury lies in the very real probability that the jury will infer that the accused is a violent person disposed to committing crimes of violence, particularly when he is accused of a violent crime. Illinois v. Allen, supra; Odell v. Hudspeth, 189 F.2d 300 (10th Cir. 1951); People v. Duran, supra.
There are, of course, valid instances giving rise to “exceptional circumstances” and “manifest need” which occur outside of the courtroom, either before or during the trial. Under proper circumstances a trial judge would be justified in taking extreme measures if the facts warranted them. In such cases the trial court must proceed with greater caution because it must in turn rely, not upon how it independently perceives and gauges the problem, but upon an assessment made by someone rarely free from bias, as in the instant case.
Although the trial court has greater latitude in assessing the evidence before him, including consideration of information obtained through less than normally reliable sources, he must still temper his decision so as not to unduly emasculate the constitutional right of the accused to his day in court under the presumption of innocence.11
In the absence of justifiable reasons appearing in the record, the trial court may not resort to physical restraints solely because of the character of the crime charged. We find nothing in the record which occurred before or during the trial suggesting that appellant would behave in a manner requiring such extreme measures. This is particularly true of the period between October 13, 1978, and January 8, 1979.
The State’s argument that the co-defendant’s acquittal is evidence that the jury was not negatively influenced is not persuasive. The record discloses that counsel for both defendants, as well as the State, argued to the jury that the co-defendant’s conviction was a foregone conclusion when the second trial for attempted capital murder, then pending, was conducted. The theory argued made it painfully clear to the jury that this case was appellant’s case and that an acquittal of the co-defendant would not excuse the co-defendant’s conduct on the second charge. Responding to such assurances, the jury did not hesitate to acquit, but this is not to say that they were not affected by the physical restraints.
[316]*316Cases in which an accused is inadvertently displayed to the jury under physical restraints for short periods are extremely common and such exposures have not necessarily called for reversal in the absence of some showing that prejudice was suffered therefrom. United States v. Larkin, 417 F.2d 617 (1st Cir. 1969); O’Shea v. United States, 400 F.2d 78 (1st Cir. 1968); Cline v. State, 463 S.W.2d 441 (Tex.Cr.App.1971); Garcia v. State, 435 S.W.2d 533 (Tex.Cr.App.1968); Xanthull v. State, 403 S.W.2d 807 (Tex.Cr.App.1966); Mouton v. State, 155 Tex.Crim.R. 450, 235 S.W.2d 645 (1950); State v. Crockett, 262 La. 197, 263 So.2d 6 (1972); Commonwealth v. Parry, 1 Mass. App. 730, 306 N.E.2d 855 (1974); Dixon v. State, 27 Md.App. 443, 340 A.2d 396 (1975); Rush v. State, 301 So.2d 297 (Miss.1974); State v. Crawford, 539 S.W.2d 633 (Mo.1976); Scott v. State, 88 Nev. 682, 504 P.2d 10 (1972); State v. Jones, 130 N.J.Super. 596, 328 A.2d 41 (1974); State v. Foster, 83 N.M. 128, 489 P.2d 408 (1971).
Exposure to the jury under physical restraints for the entire trial has inevitably presented the more serious problems. Our Court of Criminal Appeals has characterized it as “an infringement upon the constitutional presumption of innocence.” Moore v. State, supra; Thompson v. State, supra; Walthall v. State, supra.
In recognizing the legitimate governmental concern for security, the court in Walthall v. State stated:
All of this might have been and probably was justification for the handcuffing and the chaining of the appellant on the trip from the jail to the courthouse, but we cannot say that it authorized bringing the appellant into the courtroom so manacled in full view of the jury which was to try him.
505 S.W.2d, at 899.
From the record before us we cannot say that less stringent measures were not readily available to the court. Cf. Davis v. State, 505 S.W.2d 800 (Tex.Crim.App.1974), in which the restraining devices were removed from appellant after he had been seated for trial.
Although the Sheriff of Atascosa County characterized appellant as a dangerous prisoner and his jail as inadequate to house one accused of such serious crime, we note the sheriff’s expression of concern at the expense of housing appellant and his brother, in his testimony relating to the transfer to a more secure jail. We also note that in Freeman v. State, supra, the defendant was convicted of capital murder occurring in Atascosa County, but the same sheriff had no apparent complaint about the security problems inherent in the county jail building.
Unlike the case at bar, in Freeman the trial court record noted that the defendant had made actual and direct threats of violence to the sheriff on or very near to the trial date and further evidenced a continuing threat to commit acts of violence. The facts of that case also reflect an actual escape from custody by the defendant.
The facts in the instant case do not reflect an immediate or current necessity such as to support the extreme measures adopted and implemented.12
We note also that counsel for both defendants had advised the trial court of an intent to present possibly conflicting defenses. Neither defendant in fact testified [317]*317and the evidence presented by the defense was negligible at best.
Without expressing an opinion whether appellant or his brother had testimony to present, we are unwilling to believe that the presence of handcuffs had no appreciable effect on their election to not testify. The detrimental effect of such visible physical restraints upon the mental faculties does not escape us. Neither are we willing to believe that the presence of physical restraints had no effect at the punishment phase.
We think it was an abuse of discretion for the court to employ restraints without specifically finding a manifest need, when less drastic security measures would have adequately and reasonably addressed the problem.
In view of the action taken by this court herein, we deem it unnecessary to address appellant’s remaining grounds of error complaining of the trial court’s undue restriction of jury voir dire. Suffice it to mention that the constitutional guarantee of the right to be represented by counsel carries with it the right of counsel to interrogate prospective jurors in such a manner as to effectuate the intelligent exercise of peremptory challenges, but the trial court must retain some discretion in limiting the examination of prospective jurors or some trials would never terminate. Freeman v. State, supra.
The judgment is, accordingly, reversed and the cause remanded to the trial court.
