Rodney King, whose beating by Los Angeles police in 1991 was caught on camera and sparked riots after four police officers were acquitted, was found dead at the bottom of his swimming pool Sunday, authorities said. He was 47.

Police in Rialto, California, received a 911 call from King's fiancee, Cynthia Kelly, about 5:25 a.m. Once emergency personnel arrived, they found King at the bottom of the pool. He was pulled to the surface, but attempts to revive him were unsuccessful and he was pronounced dead at a local hospital.

Authorities say there were no signs of foul play, but an autopsy will be conducted.
