Tyson Must Stay in Ohio While Under Investigation

Mike Tyson, on probation for a 1992 rape conviction, was restricted Thursday to his home state of Ohio while police investigate a complaint he sexually assaulted a woman at a Chicago nightclub.

Tyson, the World Boxing Council heavyweight champion, could be ordered back to prison if he is found to have violated the terms of his release.

During the investigation in Chicago, Tyson may leave Ohio only for emergencies or for other reasons approved in advance, said George Walker, chief probation officer for Marion County. If the investigation extends into his next fight, July 13 against World Boxing Assn. champion Bruce Seldon, Tyson will be allowed to travel to Las Vegas for the bout.
