 Las Vegas police arrested O.J. Simpson on Sunday amid an investigation into an alleged armed robbery at a hotel in Las Vegas, Nevada, a source close to the investigation said.

The charges he faces are unclear.

Simpson was arrested at his room in the Palms Casino Resort in Las Vegas, the source said.

On Saturday, Las Vegas police arrested Walter Alexander and seized two guns in connection with the alleged armed robbery, the source said.

“I don’t know why they arrested him,” Simpson said Sunday. “I’ve stayed in contact with the police and the truth will come out.”

Simpson had already been questioned during the investigation into several items of sports memorabilia that were taken from collectors at a room in the Palace Station Hotel and Casino. Simpson has said the items belonged to him.
