Ordered that the order is affirmed, without costs or disbursements.
The appellant's contention that the court should have suppressed the vials recovered from his person at the time of his arrest because the testimony of the arresting officer at the Mapp hearing was incredible is without merit. Issues of credibility are primarily for the hearing court, and its findings should not be disturbed unless they are clearly unsupported by the record ( see, People v Brown, 193 AD2d 612; see also, People v Bailey, 179 AD2d 662,; People v Harley, 139 AD2d 665). The arresting officer testified without contradiction that, from a distance of several feet, he saw the appellant holding a plastic bag in which there were a number of vials containing what appeared to be cocaine. Thus, the record supports a determination that the officer had probable cause to arrest the appellant and to seize the vials. It was within the hearing court's broad discretion to limit the scope of the cross examination of the arresting officer on collateral matters designed solely to impeach his credibility. There was no improvident exercise of that discretion in this case, and the hearing court's determination will not be disturbed ( see, People v Schwartzman, 24 NY2d 241, 245, cert denied 396 US 846; see also, People v Griffin, 194 AD2d 738).
