MALIBU, Calif. (AP) — Another Hilton has landed in the gray-bar hotel. Paris Hilton's younger brother, Barron, was arrested Tuesday on suspicion of drunken driving, authorities said.

Barron Hilton, 18, was stopped after a witness reported seeing a black Mercedes-Benz weaving on the Pacific Coast Highway, at times drifting into the oncoming lane, according to the Los Angeles County Sheriff's Department.

Deputies arrested Hilton after he pulled over and got out of the car. He was booked in Malibu, where he registered a blood-alcohol level of 0.14 percent, authorities said. The legal limit in California is 0.08 percent.

He had a female passenger in the vehicle who had apparently been driving earlier and might have been involved in an accident, the Sheriff's Department said. She was not identified, and a call to the California Highway Patrol, which was investigating the woman's role, was not immediately returned.

Hilton was carrying a fake driver's license and was also arrested for investigation of carrying a falsified state document, said sheriff's spokesman Steve Whitmore.

The Sheriff's Department did not know whether he had a lawyer. There was no immediate response to a telephone message left for a Pasadena attorney who represented Paris Hilton in her drunken-driving case.

Barron Hilton was released from jail shortly before 6 p.m. Tuesday on $20,000 bail and was to be arraigned in April, Sgt. Diane Hecht said.

As word of his arrest spread, nearly a dozen paparazzi photographers swarmed the sheriff's station.

Paris Hilton pleaded no contest last year to alcohol-related reckless driving and was sentenced to 45 days in jail. The 26-year-old reality show star and hotel heiress served a little more than two weeks.
