Appellant was charged in a multi-count indictment with the offenses of first-degree armed burglary, armed robbery and related offenses occurring on November 21, 1976, as well as with counts of armed robbery and related offenses occurring on November 22, 1976. The trial court granted appellant’s motion to sever the counts, and separate jury trials resulted in his conviction of first-degree burglary while armed and armed robbery in the November 21 incident and of armed robbery in the November 22 incident. On this appeal from the convictions at both trials, appellant raises a number of contentions, only one of which we find calls for extensive consideration. This is his contention that his Sixth Amendment right of confrontation was violated during his trial for the November 22 armed robbery when the trial court refused to strike the direct testimony of Martha Ellis, upon motion, after the witness had invoked her Fifth Amendment privilege against self-incrimination on several occasions during cross-examination. 1 In Part I of this opinion, we set forth the pertinent facts from appellant’s trial for the November 22 armed robbery. In Part II, we address appellant’s main legal contentions as to the November 22 robbery and hold that the trial court committed reversible error in failing to preserve appellant’s right of confrontation. We affirm appellant’s conviction for the November 21 robbery.
I
The prosecution’s evidence showed that appellant, armed with a sawed-off shotgun
The defense theory was that the charges had been fabricated in revenge for appellant’s failure to pay for some marijuana he had obtained from Milton Blue and/or Martha Ellis. Defense witnesses represented the incident as having simply been an unarmed visit by appellant to the apartment Ms. Ellis and Mr. Blue shared to resolve the claim Mr. Blue purportedly had against him.
Police photographs showed, and Ms. Ellis and Mr. Blue admitted, that marijuana was being grown in their apartment at the time of the robbery. When appellant’s counsel asked Ms. Ellis during cross-examination whether she or Milton Blue had ever sold marijuana to appellant in the several months preceding the robbery, she asserted her privilege against self-incrimination and declined to answer. The trial court sustained her invocation of the privilege.
Appellant moved to strike Ms. Ellis’ direct testimony following her invocation of her Fifth Amendment privilege on cross-ex-animation. 2 The trial court held that the testimony sought was collateral and went to the witness’ general credibility, not to the substance of her testimony on direct.
Appellant otherwise had full cross-examination as to Ms. Ellis’ version of the events, including Ms. Ellis’ previous acquaintance with him (appellant had visited the Ellis-Blue apartment on three or four previous occasions), and the source of the stolen marijuana and the potted marijuana plants in her apartment. Milton Blue never asserted his Fifth Amendment privilege during cross-examination and denied ever engaging in a marijuana transaction with appellant.
II
Appellant’s primary contention on appeal is that, by refusing to strike the direct testimony of witness Martha Ellis, upon motion, after she had invoked the Fifth Amendment on several occasions during cross-examination, the trial court violated his Sixth Amendment right to confrontation.
The opportunity for a defendant to cross-examine a witness is a matter of right.
Davis v. Alaska,
“Some meaningful degree of cross-examination must be allowed in the first instance in order to comply with the Sixth Amendment’s command in this regard.”
Springer v. United States, supra
at 854. Where, as here, a defendant seeks to have a witness’ direct testimony stricken because cross-examination of the witness was restricted, the issue is committed to the discretion of the trial court to be exercised pursuant to appropriate legal standards.
United States v. Cardillo,
The cross-examination of a witness, or presentation of evidence, as to his or her bias or motive is a more particularized, and potentially more damaging, way of calling into question a witness’ credibility, Davis
v. Alaska, supra
In the present case, as in United States v. Demehak, United States v. Newman, and United States v. Lester, the cross-examination of the key prosecution witness by the defendant was cut off in limine with respect to a crucial line of questioning concerning the witness’ bias or motive to testify. Martha Ellis was the complainant and one of only two witnesses to observe the incident in question in its entirety. Her testimony was of crucial, and perhaps determinative, importance to the prosecution’s case. As there was no question that appellant had been present at the time the confrontation between himself and Martha Ellis took place, the only issue to be decided was the nature of that confrontation: whether it was an armed robbery, as Ms. Ellis claimed, or whether it was merely an unarmed visit, as appellant suggested.
Through his cross-examination of Ms. Ellis, defense counsel attempted to elicit testimony as to whether appellant has purchased any marijuana from the witness or from her boyfriend and roommate, James Milton Blue, in the several months preceding the alleged robbery. In particular, defense counsel was interested in whether appellant had ever purchased a large quantity of the substance and then failed to pay for it. From such testimony counsel would then have sought to convince the jury that Ms. Ellis and Mr. Blue had subsequently called in the police on the pretext that an armed robbery had taken place in order to utilize the system of justice as an instrument of retaliation against appellant for having failed to pay for the supply of marijuana he had received from them. However, when defense counsel attempted to cross-examine Ms. Ellis along this line, the witness repeatedly invoked her Fifth Amendment privilege against self-incrimination. See text, supra note 2. By reason of Ms. Ellis’ continuing refusal to answer questions concerning whether she or Milton Blue had ever sold marijuana to him, appellant was effectively precluded from examining the witness as to a motive she may have had for testifying against him.
While appellant possessed, and fully exercised, a right to present extrinsic evidence in support of his theory, he also had an unquestioned right to develop his case through cross-examination of the government’s witnesses, for there could be nothing more basic to appellant’s attempt to demonstrate from her own testimony that Ms. Ellis did indeed have a very strong motive for being hostile towards and testifying against him.

v.

v.
Lester.
Without such evidence before the jury, they would not be in possession of a sufficient amount of information concerning formative events to allow them to make a “discriminating appraisal”,
United States
v.
Blackwood,
Accordingly, we hold that the trial court erred in refusing to grant appellant’s motion to strike the direct testimony of Martha Ellis in its entirety. We reverse the judgment of the lower court with respect to appellant’s conviction for the alleged armed robbery of November 22 and remand for a new trial.' The judgment of conviction as to the November 21 robbery is affirmed. 3
Reversed and remanded.
Notes
. Appellant presents two further issues for our consideration. First, appellant contends that at his trial for the November 22 robbery, he should have been allowed to call as a defense witness one Jerry Jones. Mr. Jones would have testified that he had purchased marijuana from the prosecution’s witness, Martha Ellis, at some time prior to the robbery. We fail to perceive how this evidence would have implicated Ms. Ellis’ bias against appellant or her motive to fabricate a story about the incident. Rather, the evidence would have merely called into question Ms. Ellis’ general credibility. Generally, a party is bound by a witness’ answer on cross-examination with respect to collateral matters, such as general credibility, and may not introduce extrinsic evidence to contradict the testimony. The trial judge in the instant case properly exercised his discretion in refusing to allow Mr. Jones to testify.
See Tinker v. United States,
Appellant also contends that at his trial for the robbery of November 21, 1976, the prosecutor’s closing argument to the jury impermissi-bly referred to appellant’s failure to testify, thereby violating his Fifth Amendment right. Timely objection was made by defense counsel. This issue is governed by the two-prong test adopted in Peoples v. United States, D.C.App.,329 A.2d 446 , 450 (1974). See Wright v. United States, D.C.App.,387 A.2d 582 (1978); Brown v. United States, D.C.App.,383 A.2d 1082 , 1085 (1978). Evaluating the comments of the prosecutor in context and applying the Peoples rule, we affirm the trial court’s finding of no impropriety on the part of the prosecution.
. The pertinent part of the transcript reads:
Q. [DEFENSE COUNSEL]: Has [appellant] ever come up there and bought any marijuana from you or Milton?
A. I would take the fifth on that.
[GOVERNMENT]: Objection as to time.
[DEFENSE COUNSEL]: Just a minute. She just said she claims the fifth amendment. I will honor that.
Q. [DEFENSE COUNSEL]: Do you claim your privilege under the fifth amendment not to incriminate yourself?
A. Yes, I do. [Tr. 353-54]
After a lengthy bench conference, the trial court allowed further questioning by defense counsel.
Q. Was there any marijuana or any drugs sold by anybody up there to Mr. Johnson in the month of October, 1976?
A. I will take the fifth.
Q. In the month of November?
A. I will also take the fifth.
Q. And August and September of 1976?
A. I will take the fifth.
[THE COURT]: Counsel, approach the bench. [Tr. 357]
The court then directed counsel to terminate that line of questioning [Tr. 358]. Counsel thereafter continued his cross-examination of Ms. Ellis.
