LOS ANGELES - Andrew Getty, an heir to the Getty oil fortune, was found dead at his Hollywood Hills home Tuesday.

The cause of death was undetermined at the time, Sgt. Kyle Kirkman of the Los Angeles Police Department said.

Police were called to the home, at the end of a narrow, leafy street, at 2:18 p.m., Cmdr. Andrew Smith said.

A woman who was present at the time of the death was escorted from the residence by police for questioning, Smith said. She is cooperating with investigators, Smith said.

Los Angeles police robbery-homicide detectives were handling the case because of its high-profile nature, a law enforcement source told the Los Angeles Times.

Just two weeks ago, Getty sought a restraining order against a woman, according to court records. His attorney declined to comment.

Authorities, including representatives from the Los Angeles County Coroner's Office, were converging on the compound Tuesday afternoon.

Andrew Getty, 47, was the grandson of oil baron J. Paul Getty and part of the Getty trust. He was one of four sons of Gordon P. Getty, one of J. Paul Getty's three sons. Gordon Getty has a net worth of $2.1 billion, according to Forbes magazine.

In 1996, Andrew Getty purchased the 70-year-old Hollywood Hills villa of three-time Oscar-winning film composer Miklos Rozsa.
