Opinion by
On the night of April 14-15, 1972, two opposing groups of boys from two Philadelphia communities gathered on opposite banks of Wissahickon Creek awaiting the opening of trout season. Name calling, rock throwing and sporadic small fights inevitably led to a massive retaliatory attack by the group to which the appellant Jennings belonged. During the assault one youth, Gerald Clemson, was beaten and stabbed several times. While no one could positively identify Jennings as being directly involved in the beating and stabbing of Clemson, he was identified as having chased the victim across the creek immediately thereafter while brandishing a weapon 1 and shouting, “If you want more, come back.”
During the trial the appellant called one Thomas Vecchione who had been present on the night in question, and who was to be the principal defense witness. 2 Before the witness entered the courtroom, the assistant district attorney informed the court that there was an unexecuted complaint outstanding against the witness and that if he testified “he (would) no doubt incriminate himself.” The assistant district attorney then advised the court that whether an arrest warrant would issue depended in large part on whether the witness testified. The Commonwealth admitted that it was only charging Vecchione with being a participant in the general assault, a role which twenty to thirty other *491 youths had also played, and for which no one had been prosecuted theretofore. Thus, virtually every exculpatory witness that the appellant could call was susceptible to a similar threat. When Vecchione entered the courtroom he was apprised of the complaint and its implications. The discourse between the district attorney and the court led Vecchione to state on the stand that he was “intimidated” and “scared of” the prosecutor. The court advised Vecchione to confer with an attorney during a recess period. After a noon conference with a member of the public defender’s office, Vec-chione went home and did not return to court. Out of consideration for Vecchione’s plight, the appellant expressly declined the court’s offer to issue a bench warrant to procure Vecchione’s return.
The events which occurred at trial surrounding the circumstances and significance of the criminal complaint against Vecchione led the trial judge to express some rather harsh words for the assistant district attorney: “Frankly I have never had this experience before, either. I don’t think I have ever seen a more blatant abuse of the criminal process than what occurred here this morning. I am really shocked. . . . Threatening with an arrest. In my many years as a Judge and seven years as a prosecutor myself, and — I have never had an experience like this. ... I want to turn this tactic. ... I am going to have the notes transcribed. I will refer it to the proper authority. . . . This is outrageous.”
The appellant argues that the actions of the prosecutor constituted a denial of the appellant’s Fourteenth Amendment rights to due process and a fair trial. We agree. The district attorney contends that his remarks were meant solely as a matter of protection for Vecchi-one against testimony which might incriminate him.
Pyle v. Kansas,
The landmark decision of
Brady v.
Maryland

delineated the guidelines for determining whether the state has unconstitutionally suppressed evidence, and concluded: “We now hold that the suppression by the prosecution of evidence favorable to an accused upon request violates due process where
the evidence is material either to guilt or punishment, irrespective of the good faith or bad faith of the
prosecution.”

Thus, the question posed by the instant appeal is whether the prosecutor’s conduct constituted a suppression of evidence within the intendment of
Pyle
and
Brady.
We are of the opinion that it did. It has been established that the requisite warnings may not be given in a fashion which exert “such” duress on the witness’ mind as to preclude him from making a free and voluntary choice whether or not to testify.”
Webb v. Texas,
Finally the Commonwealth makes the novel argument that it is somehow compelled by
Escobedo v. Illinois,
And finally this unfortunate occurrence in the process of the trial did not constitute harmless error. Vec-chione’s testimony, as apparently agreed upon by both the district attorney and the appellant, could very well have so weighed in favor of the defendant as to result in a verdict favorable to defendant, or at least a lighter sentence.
*494 The decision of the lower court denying appellant’s motion for a new trial is hereby reversed, and the cause remanded for a new trial.
Notes
Some witnesses said the weapon was a knife, although there was testimony that it was a club.
The appellant’s brief indicates that had Vecchione testified he would have given evidence tending to prove that Jennings did not participate in the assault upon Clemson and did not know that Clemson was stabbed when he chased him.
