Former heavyweight contender Mitch Green was arrested...

Former heavyweight contender Mitch Green was arrested for the second time in one week and charged with beating his girlfriend.

Police arrested Green late Saturday after a woman complained she was struck by the boxer at her nearby Harlem apartment, said Sgt. Maurice Howard, a police spokesman, who identified the woman only as being 32 and the mother of Green’s child.

Green, 31, who was to be held overnight on a third-degree assault charge, sparred with the law earlier in the week when he was arested Wednesday for an alleged outburst on a Harlem street corner. Emergency Service Unit officers used a stungun to subdue the boxer.

Green, who lives in Jamaica, Queens, was in a brawl with heavyweight champion Mike Tyson Aug. 23 in Harlem, suffering cuts and a swollen left eye and leaving Tyson with a broken hand.
