— Appeal by the defendant from a judgment of the Supreme Court, Queens County (Clabby, J.), rendered June 14, 1984, convicting him of attempted murder in the second degree, assault in the first degree, and criminal possession of a weapon in the second degree, upon a jury verdict, and imposing sentence.

It was error for the trial court to deny defense counsel the opportunity to cross-examine the complainant about her 1969 conviction of assault in the third degree (see, People v Allen, 67 AD2d 558, affd 50 NY2d 898). The complainant’s credibility was a crucial issue in this case because of the conflicting testimony about the circumstances of the shooting. Therefore, this error cannot be considered harmless (see, People v Watson, 111 AD2d 888; cf. People v Batista, 113 AD2d 890; People v Allen, supra).
