CHATTANOOGA, Tenn. (AP) - A former Chattanooga police sergeant fired for having sex with a woman in his patrol car has agreed to dismiss his racial bias lawsuit against the city.

Court records show former police Sgt. Patrick Welles agreed to the Tuesday dismissal of his federal lawsuit.

A city attorney declined comment and Welles' attorneys could not be reached Friday.

The motion to dismiss says all matters in dispute "have been resolved."

Investigators say the 12-year police veteran got a call for backup one night in 2004 and told the dispatcher he was busy but would be there shortly. It turned out he was busy having sex with a woman in his patrol car.

Welles' racial discrimination lawsuit said white colleagues on the Chattanooga force did similar things - or worse - and were allowed to keep their jobs.
