The break-in was reported at the Palace Station casino late Thursday, police spokesman Jose Montoya said.
Simpson was released and is believed to be in Las Vegas, Montoya
said. "We don't believe he's going anywhere," he said.
A Simpson attorney in Florida, Yale L. Galanter, did not immediately return phone messages seeking comment.
The Heisman Trophy winner and ex-NFL star had been scheduled to
give a deposition Friday in Miami in a bankruptcy case involving his eldest daughter. But it was canceled because Simpson had told attorneys that he would be out of town.
Las Vegas police said investigators also questioned the alleged
victims in the incident.
Montoya said the investigators report would be turned over to
the Clark County district attorney on Friday. The district
attorney's office would then decide whether to pursue an arrest
warrant in the case.
