Paris Hilton's younger brother Conrad has been charged in Los Angeles with allegedly stealing a car and violating an ex-girlfriend's restraining order.

Police went to the Hollywood Hills home of the 23-year-old's ex-girlfriend, Hunter Daily Salomon, before dawn on Saturday.

According to reports, Conrad Hughes Hilton - who is the heir to the Hilton Hotel empire - was found in a Bentley owned by the father of his former girlfriend.

He has been charged with one felony count of driving or taking a vehicle without consent, two misdemeanour counts of violating a restraining order and one of contempt of court.

William Bell, 21, is also charged with stealing the car.

Hunter's father is Rick Salomon, who once dated Paris Hilton and appeared in an infamous sex tape that propelled the heiress into the spotlight.

Salomon has also been twice married and divorced to former Baywatch star-turned campaigner Pamela Anderson.

Conrad is due in court later and Bell on 1 June.
