Former American football star OJ Simpson has been interviewed by police over his alleged involvement in a robbery at a Las Vegas casino.

The robbery that took place in a hotel room was reported by a memorabilia dealer who claimed that weapons were involved in the heist of his sporting goods.

The police said the former professional sportsman was cooperating with them and that they were investigating reports that guns were used in the confrontation.

Police captain James Dillon said: "We have a report from the victim that there were weapons involved. We have not determined that at this time and have not recovered any weapons."

"The items taken were various sports-related products," he added.

Mr Simpson was cleared in 1995 of murdering his ex-wife and her friend in a case which raised questions about the justice system in the United States.

He was later convicted in a civil trial which held him liable for the deaths and ordered him to pay $33.5m (£17m) in damages to the families of those he was acquitted of killing.

The incident comes two days after the release of a book If I Did It in which Mr Simpson considers how he may have killed his former wife and her friend Ronald Goldman.
