Defendant was convicted by a jury of kidnapping, MCL 750.349; MSA 28.581, and conspiracy to kidnap, MCL 750.157a; MSA 28.354(1). He was sentenced to concurrent terms of 2 to 5 years in prison on each count.
Defendant appealed and, in an unpublished opinion per curiam, we reversed on two grounds. We concluded that the prosecutor’s comments in closing argument that defendant’s presence at trial afforded him an opportunity to fabricate a story and the prosecutor’s questioning of defendant regarding his financial condition required reversal. Docket No. 54321, decided May 2, 1984.
The Supreme Court granted leave,
I
We begin by reconsidering whether the questions concerning defendant’s financial condition constitute error mandating reversal. In
People v Henderson,
In the instant case, defendant was an attorney and was seeking to obtain money from the victim, David Nixon. On cross-examination, the prosecutor questioned defendant about whether he was in serious financial trouble at the time of the kidnapping and whether defendant had over $250,000 in debts. Defendant denied any financial difficulty. The prosecutor then asked whether defendant ever *830 was in debt for that amount. Defense counsel objected to evidence of financial difficulty at times other than at the time of the abduction, but the trial court permitted an answer. Defendant again denied being in debt.
We adhere to our original conclusion that the prosecutor’s questions concerning defendant’s financial condition at times other than that of the kidnapping were improper. 1 However, upon reconsideration, we no longer hold the view that the error requires reversal. The only question which concerned a time other than that of the kidnapping was whether defendant had ever owed $250,000, which defendant denied. We conclude that this did not prejudice defendant.
Defendant also raises three additional allegations of prosecutorial misconduct. The first, regarding Nixon’s testimony that defendant asked him not to implicate Doug Suess, was not objected to and appellate review is precluded.
People v Hooks,
Defendant challenges the questioning of his secretary, Charlene Crouch, about whether she heard discussions regarding illegal activities at defendant’s office. Following a defense objection, the question was withdrawn. Defendant also challenges the questioning of Crouch on redirect examination regarding whether she had reason to believe defendant was involved in the abduction of Nixon. However, it was defendant who initially brought up the issue of Crouch’s opinion of defendant’s guilt. We find no prejudice in either of these instances.
II
On appeal, defendant challenges the sufficiency
*831
of the evidence to support a guilty verdict on the charges of conspiracy to kidnap and aiding and abetting a kidnapping. With regard to the conspiracy charge, there certainly was evidence that defendant intended to combine with Postelwaite and Snyder and specifically intended to kidnap Nixon. See
People v Atley,
Ill
Defendant argues that his convictions should be set aside because they are based on testimony the prosecutor knew was false and perjured. This Court has held that reversible error is presented when a prosecutor knowingly presents false testimony.
People v Thornton,
Unlike Thornton, in this case the prosecutor made no attempt to conceal the fact that Nixon was lying. Moreover, there is no indication, other than the inconsistencies in the preliminary exam testimony, that the prosecutor knew until the day before trial that Nixon had perjured himself. Finally, the version presented at trial was the least helpful to Nixon’s credibility and, since it differed from his prior testimony, afforded defense counsel *832 an opportunity to impeach Nixon. We find no prejudice to defendant.
IV
Defendant next argues that the trial court reversibly erred by refusing to order the prosecutor to obtain documents from federal and out-of-state authorities. Although the modern trend in Michigan is towards broader criminal discovery, 2 we do not believe that this broader discovery extends to requiring the prosecutor to undertake discovery on behalf of defendant. Defense counsel acknowledged that the prosecutor made his entire file available. That exceeded the requirements placed on the prosecutor. 3 The trial court did not err.
V
Defendant’s next argument is that the prosecutor breached an agreement not to charge him with kidnapping. A hearing was held below and the trial court concluded that either there was no definite agreement or, at most, there was an agreement not to charge defendant with kidnapping if he pled guilty to certain federal charges. Defendant made no such plea. The trial court’s decision was not erroneous.
VI
Defendant next complains that the trial court improperly instructed the jury. Defendant argues that the trial court’s instructions regarding specific intent were confusing, the instruction on aiding and abetting was ambiguous, and that the *833 trial court erred in failing to reinstruct the jury on the definition of specific intent.
With respect to the aiding and abetting instruction, defendant failed to object to the instruction at trial, thus precluding appellate review.
People v Haney,
VII
Defendant next argues that reversal is required because Crouch indicated a willingness to undergo hypnosis to refresh her memory. However, the remark was made during defense counsel’s cross-examination of Crouch, it was stricken from the record, and the trial court offered to give a curative instruction which defendant declined. There is no basis for reversal.
VIII
Defendant argues that the prosecutor failed to produce a res gestae witness, namely a waitress in a restaurant that defendant, Crouch and Kenney lunched at during the time Nixon was being held. However, Kenney did not indicate that the kidnapping was discussed at the lunch and defendant and Crouch specifically stated that the abduction was not discussed. At no time did defendant move for endorsement. The waitress observed no part of the criminal transaction, and there is not any connec
*834
tion between the waitress and the crime beyond the possibility of overhearing statements which defendant denies were made. See
People v Carter,
IX
Defendant argues that a remand is necessary to consider newly discovered evidence that casts doubt on the truthfulness of certain testimony material to the prosecutor’s case. Defendant’s request for a remand on this issue is supported by an affidavit of one of defendant’s clients, James Lafler. However, the affidavit only raises issues concerning the credibility of certain prosecution witnesses, it does not directly relate to defendant’s guilt. Newly discovered evidence which relates only to witness credibility is not sufficient to require a new trial.
People v Boynton,
X
Defendant next argues that a remand is necessary to determine the existence and importance of evidence of concessions made to a prosecution witness. This argument is again based upon new evidence related to witness credibility. No remand is required. Boynton, supra.
XI
Defendant also argues that a remand is required to determine if he was denied effective assistance of counsel due to an alleged conflict of interest arising from his counsel’s cooperating with the counsel of codefendants who ultimately turned *835 state’s evidence. However, defendant has failed to show any basis for prejudice on this issue, and remand is not required.
XII
Defendant next argues that a remand is necessary to determine if there has been a violation of the Interstate Agreement on Detainers Act (IAD), MCL 780.601; MSA 4.147(1). However, defendant never requested a final disposition of his case as required by MCL 780.601, Art III, ¶ (a); MSA 4.147(1), Art III, ¶ (a). Moreover, none of defendant’s claimed violation of the IAD relates to delays after December 1, 1978, when he first became a federal prisoner. Until that time, the IAD was inapplicable. No remand is required.
XIII
This brings us to defendant’s final claim of error: that a remand is necessary to determine whether the jury was improperly influenced when "the trial prosecutor took heroic action to protect the court’s personnel including the jury” when a tornado struck downtown Kalamazoo on May 13, 1980. Defendant concedes this is a novel issue. While admitting the prosecutor’s conduct was commendable, defendant is concerned it may have influenced the jury to the prosecutor’s favor. When the proceedings resumed a week later, defendant was afforded an opportunity to place anything on the record concerning the interruption in the proceedings. Defense counsel made no objections.
We agree the issue is novel, but find no basis for reversal.
Affirmed.
