King, whose videotaped beating by Los Angeles cops touched off three days of riots that killed 53 and wounded 2,000 after the officers involved were acquitted by a white jury in 1992, whooped an ex-cop in a boxing ring near Philadelphia on Friday night, promoters said.

King, 44, who has struggled with drugs and alcohol since his beating, pulled it together to win after three rounds against tattooed and mohawked ex-cop Simon Aouad at the Philadelphia airport Ramada.

“This is a new chapter in my life,” King said, according to a statement by the promoter. “I am sober, fit and now a winner.”
