Las Vegas ? Prosecutors filed formal charges Tuesday against O.J. Simpson, alleging the fallen football star committed 10 felonies, including kidnapping, in the armed robbery of sports memorabilia collectors in a casino-hotel room.

Simpson was arrested Sunday after a collector reported a group of armed men charged into his hotel room and took several items Simpson claimed belonged to him. Police reports obtained Tuesday by The Associated Press offered details on the scene.

Simpson, 60, was booked on five felony counts, including suspicion of assault and robbery with a deadly weapon. District Attorney David Roger filed those charges and added five other felonies, including kidnapping and conspiracy to commit kidnapping, according to court documents.

Simpson, accused along with three other men, faces the possibility of life in prison if convicted in the robbery at the Palace Station casino. He was being held without bail and was scheduled to be arraigned today.
