LOS ANGELES •A 21-year-old man drowned in the swimming pool of the Beverly Hills home of actress Demi Moore, news reports said on 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.

The newspaper quoted Sergeant A. Bone of the Los Angeles Police Department as saying that Moore was not at home at the time.

"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.

In a statement, Moore, 52, said: " I am in absolute shock."

A neighbour told website TMZ that her three children with former husband Bruce Willis have been staying at the house and throwing "parties every day, day and night".

However, law enforcement said no one from Moore's family was present when the body was found.
