The police arrested Simpson on Sunday, saying he was part of an armed group that burst into a Las Vegas hotel room and snatched memorabilia that documented his storied career.
Simpson said it was merely a confrontation with no guns. He said autographed sports collectibles, his Hall of Fame certificate, a photograph with former FBI director J. Edgar Hoover and video from his first wedding were all his, and that they were stolen from him and were about to be fenced by unethical collectors. the police said they were not sure who owned the memorabilia. But they say the manner in which the goods were taken was under investigation.
"Whether or not the property belonged to Simpson or not is still in debate," Lt Clint Nichols said on Sunday.
"Having said that, the manner in which this property was taken, we have a responsibility to look into that, regardless of who the property belonged to."
After being whisked away in handcuffs, Simpson was booked at the county jail on Sunday night on two counts of robbery with a deadly weapon, two counts of assault with a deadly weapon, and conspiracy to commit a crime and burglary with a firearm, the police said.
The district attorney said he expected Simpson to ultimately be charged with seven felonies and one gross misdemeanour. If convicted of the charges, Simpson would face up to 30 years in State prison on each robbery count alone.
A judge ordered Simpson be held without bail, Sgt John Loretto said. A court date was set for Thursday.
