LOS ANGELES (AP) _ Former Cincinnati Bengals running back Stanley Wilson has been released from custody because authorities did not have the evidence to charge him with robbery, police said.

Wilson, who was banned from the NFL last year for cocaine use, was released Friday, two days after his arrest in connection with an Oct. 10 purse snatching, Sgt. Dan Pugel said.

''There was probable cause for the arrest, however there was insufficient evidence to file charges with the district attorney,'' Pugel said.

The victim was unable to identify Wilson as the robber, Detective Chuck Hart said.

Wilson was arrested Wednesday night in the Los Angeles suburb of Wilmington after officers stopped him in a car which witnesses identified as the one used in the purse snatching.

Wilson told police his car might have been used in the robbery because he lent it to someone, but he could not remember that person's name, Hart said.

Wilson was banned from the NFL for using cocaine the night before the 1989 Super Bowl between the Bengals and the San Francisco 49ers. He was not allowed to play in the game.

Wilson also was arrested last January in Gardena for scuffling with officers and possessing drug paraphernalia.

He missed the 1985 and 1987 NFL seasons for violating the league's drug policy and entered a Phoenix drug clinic in 1989.

ROCHESTER, N.Y. (AP) - Roger Bowker moved within one victory of his first Professional Bowlers Association title since 1988 by taking the top seed after 42 games of qualifying at the $150,000 Chevy Truck Classic.

Bowker, of Ocala, Fla., felled 10,001 pins in the 42 games for an average of 238.1. Runner-up Hugh Miller of Seattle was 23 pins behind when the preliminaries concluded Friday.

Miller, seeking his sixth career title and second this year, is guaranteed a berth in the semifinal of the stepladder format against one of three other qualifiers.

Kiszewski later earned the No. 4 seeding with a 39-38 victory over Husted in a two-frame roll-off.
