OPINION
This is аn appeal, by allowance, from the order of the Superior Court,
*528 Appellant claims the trial court erred in permitting a defense witness, Allen Page, to be excused from testifying because of the witness’ assertion of his Fifth Amendment privilege. In this context, appellant alleges that the trial court should not have excused the witness without first establishing the factual basis of the asserted privilege; that the prosecutor engaged in misconduct by threatening prosecution which coerced the witness into invoking his privilege; and that trial counsel was ineffective 2 for failing to establish on the reсord the nature of the defense witness’ anticipated testimony and in failing to question the witness to ascertain whether the threat of prosecution influenced the witness’ decision not to testify. Finally, appellant claims counsel was ineffective fоr failing to call a co-defendant as a defense witness after the court entered a directed verdict of not guilty in favor of the co-defendant upon the conclusion of the Commonwealth’s case. For the reasons that follow, we affirm the judgments of sentence.
The underlying facts of the instant appeal are as follows: In the early morning hours of November 15, 1977, Allen Page met Luther McCray in a restaurant and asked if McCray and another individual, Carlos Heath, who was with McCray, would assist Page in removing thе remainder of Page’s belongings from McCray’s apartment. Page had lived in McCray’s apartment but previously moved to another apartment on north 20th Street in Philadelphia.
When Page, McCray and Heath arrived at Page’s new residence on 20th Street, Page yelled up to the second floor window. Appellant, Johnny Allen, also a resident at the 20th Street location, looked out the window and subsequently came down to admit the three men. Page was the last to enter. Immediately thereafter, apрellant slammed the door behind McCray, Heath and Page and proceeded to pull out a butcher knife. Appellant searched and then took McCray’s money, coat and watch. Another individual, Charles Carter *529 appeared at the top of the stairs. Heath was also searched by appellant, but nothing was found. Page was neither searched nor robbed.
Appellant then allowed McCray, Heath and Page to leave after warning them not to call the police. McCray called the police from a nearby set of public telephones. Page simultaneously used another telephone and made a call, the contents of which could not be determined because “he tried to keep his voice down” although Heath was standing near Page. While waiting for the police, McCray flagged down a patrol car and informed the officer of the robbery. Upon arrival at the 20th Street apartment with the police, McCray identified appellant, who had chаnged his clothes, and Charles Carter. Both appellant and Carter were arrested, but the stolen items were not recovered.
Appellant and Carter were tried together. At the close of the Commonwealth’s case, the court directed a verdict of acquittal against Carter. Appellant did not testify, but defense counsel attempted to call Allen Page as a witness. The prosecutor informed the court that there was a question concerning Page’s participation in the incident, and as an officer of the court, the prosecutor suggested that counsel should be appointed to represent Page. The court appointed Walter Dinda, Esquire, to represent Page and upon conferring with Page, Mr. Dinda informed the сourt that pursuant to his (Dinda’s) advice, Page did not wish to testify and intended to assert his Fifth Amendment privilege. Page was called to the stand and the following colloquy occurred:
BY MR. SHAFFER [Attorney for appellant]:
Q Mr. Page, do you know the defendant in this case, Johnny Allen?
MR. DINDA: Objection.
BY THE COURT:
Q I think the question should be: As you know, you have been called as a witness in this case. Do you understand that?
A Right.
*530 Q And you have had an opportunity to discuss this matter with the lawyer who has been appointed to represent you, Mr. Dinda?
A Right.
Q It has been indicated that you do not wish to testify in this case after discussing this mаtter with your attorney; is that correct?
A Right.
Q Are you saying that if any questions are directed to you, you are going to take your Fifth Amendment privilege and not testify?
A Right.
The trial court excused Page from testifying. Defense counsel suggested that Page had been intimidated by the prosecutor with the threat of prosecution if he testified. The prosecutor stated that Page would be arrested whether or not he testified. Defense counsel apologized to the court and prosecutor and the defense then rеsted. After appellant’s trial, Page was arrested and subsequently pled guilty to robbery, conspiracy, aggravated assault, possession of an instrument of crime, and reckless endangering.
The standard against which a trial judge must determine whether a witness may properly invoke a claimed Fifth Amendment privilege was set forth in
Commonwealth v.
Carrera,
When [a witness is called to testify], he or she is not exonerated from answering questions merely upon the declaration that in so doing it would be self-incriminating. It is always for the court to judge if the silence is justified, and an illusory claim should be rejected. However, for the court to properly overrule the claim of privilege, it must be perfectly clear from a careful consideration of all the circumstances, that the witness is mistaken in the apprehension of sеlf-incrimination and the answer demanded cannot possibly have such tendency. (Emphasis in the original, citations omitted.)
Id., 424 at 553-54,227 A.2d at 629 .
*531
If an individual possesses reasonable cause to apprehend danger of prosecution, “it is not necessary that a real danger of prоsecution exist to justify the exercise of the privilege against self-incrimination.”
Id.
“Moreover, the privilege extends not only to the disclosure of facts which would in themselves establish guilt, but also to any fact which might constitute an essential link in a chain of evidеnce by which guilt can be established.”
Id. See Hoffman v. United States,
It is clear that under both our state and federal constitutions, a criminal defendant has a right of compulsory process to obtain witnesses in his favor. Pa. Const, art. I § 9.
See Washington v. Texas,
The Superior Court panel was of the opinion that the trial court did not err in allowing Page tо assert his Fifth Amendment privilege without first making a specific inquiry into the factual basis for the claimed privilege. That court found, as did the trial court, that the testimony of record was sufficient to suggest Page’s complicity in the crime. A specific factual inquiry was thеrefore deemed unnecessary. We agree.
This Court’s decision in
Commonwealth v. Rolon,
In the instant case, the record contained evidence suggesting Page’s complicity in the crime. Page was the individual responsible fоr directing McCray and Heath to the place of the robbery. Upon arrival at the 20th Street residence, Page summoned appellant. Page was neither robbed nor searched. After McCray, Heath and Page left the apartment, while McCray рhoned the police, disregarding appellant’s threats not to call, Page simultaneously made an unidentified phone call himself. When the police arrived at the 20th Street apartment shortly thereafter, appellant was wearing different сlothes and had disposed of the proceeds of the robbery. Further, the court was advised of the prosecution’s intention to arrest and try Page for these charges in addition to Page’s counsel’s conclusion that the area of inquiry would tend to inсriminate Page.
The instant invocation of Page’s Fifth Amendment privilege was properly accepted by the trial court. Guided by the facts of the case, the trial judge found that it was far from “perfectly clear” that the witness was mistaken in his apprehension of self incrimination and realized that the answers to the questions relating to the robbery possessed the possibility of incriminating Page. See Commonwealth v. Carr-era, supra. This finding by the trial judge is amply supported and will not be disturbed.
Appellant’s contention that Page’s assertion of his Fifth Amendment privilеge was a result of prosecutorial misconduct is also without merit. There is no basis in the record upon which to conclude that the prosecutor’s informing the court of Page’s suspected complicity in the crime and the suggestion that counsel be appointed to advise Page,
*533
constituted a coercive influence on Page’s decision not to testify. The prosecutor stated that Page would be arrested and charged whether or not he testified.
See Commonwealth v. DiGiacomo,
It is also significant that Page’s decision not to testify resulted from his consultation with his counsel. The presence of his counsel served as a further insulation from any intimidation which may have otherwise resulted from the prosecutor’s remarks. Such a situation is' clearly distinguishable from one where the action of a prosecutor or judge “.. . effectively dr[i]ve[s] [the] witness off the stand...”
Webb v. Texas,
Appellant next contends trial counsel was ineffective for failing to place on the record the nature of Page’s anticipated testimony and for failing to establish that the Commonwealth coerced Page into not testifying. Since we have concluded the Commonweаlth did not coerce Page, the second prong of this argument must necessarily fall. Additionally, appellant has failed to show that any purpose would be served by the preservation of the evidence sought to be obtained from Page. If the exercise of the privilege was proper, and we find that it was, no purpose can be served by attempting to memorialize it. Counsel will not be deemed ineffective for failing to pursue an action which would not inure to the benefit of his client.
Commonwealth
v.
Tarver,
Finally, appellant claims trial counsel was ineffective for failing to call a co-defendant as a defense witness after a directed verdict of not guilty had been entered by the court in the co-defendant’s favor. Appellant merely alleges that counsel’s failure to present testimony of a co-defendant,
*534
Carter, constitutes ineffective assistance of counsel. Appellant provides no factual basis supporting the conclusion that the co-defendant Carter possessed exculpatory evidence. Appellant’s implicit suggestion that because Carter was acquitted, he therefore was a favorable witness is a non sequitur. The fact that he was present and observed the event readily suggests that he may have been an eyewitness against appellant. Absent a showing that the co-defendant’s testimony would have indeed been favorable, there is no factual predicate for this claim of ineffectiveness.
Commonwealth v. Hawkins,
Judgments of Sentence affirmed.
Notes
. Appellant was convicted of robbery, aggravated assault, possession of an instrument of crime and recklessly endangering another person. Appellant was sentenced to 2-5 years on the robbery conviction. Sentence was suspended on the remaining convictions.
. Trial counsеl withdrew his representation on July 25, 1978. Present counsel, appointed by the court, filed and argued post-verdict motions.
. This writer disagreed that the record in
Rolon
did not provide a sufficient basis for the court to accept the invocation of the witnesses’ privilege against self-incrimination.
