Los Angeles: A 21-year-old man drowned in the swimming pool of the Beverly Hills home of actress Demi Moore, news reports said Sunday.
Police arrived at the scene in the early hours and found a man who was being treated by paramedics, the Los Angeles Times said, adding that the man was pronounced dead at the scene soon after.
Moore was not at home at the time, the newspaper quoted Sergeant A. Bone of the Los Angeles Police Department as saying.
"From what I understand it was a staff member," he added.
Celebrity website TMZ, citing law enforcement sources, said the man did not know how to swim and appeared to have slipped and fallen into the pool.
Police are investigating.
Moore, 52, has starred in movies including the hit "Ghost" (1990) and "G.I. Jane" (1997).
She was previously married to Ashton Kutcher and before that to Bruce Willis.
