MISCHA BARTON - MISCHA BARTON ARRESTED FOR DUI

Actress Mischa Barton has been arrested on suspicion of driving under the influence (DUI).

The 21-year old was also booked for possession of marijuana and driving without a licence, according to Los Angeles police.

Barton was driving her white Range Rover in West Hollywood when stopped by police at 02:46 local time. Police said her car was straddling two lanes of traffic and that she had failed to signal when making a turn.

She was arrested on suspicion of misdemeanour drunk driving after failing a field sobriety test.

"During Ms Barton's detention, it was determined that she was an unlicensed driver and was driving while under the influence of an alcoholic beverage," the official report added.

"Ms Barton was arrested and transported to West Hollywood Sheriff's station where the booking process was completed without incident."

Sergeant John Hocking of the Los Angeles Country Sheriff's department said the actress was also suspected to be in possession of marijuana and an undisclosed controlled substance.

Barton was jailed for around seven hours in lieu of $10,000 (£5,000) bail.

The English-born actress, best known for her role as Marissa Cooper on The OC, made her film debut in 1997's Lawn Dogs.

She also appeared in The Sixth Sense and Notting Hill and recently played a cameo role in British comedy hit St Trinian's.

Barton's arrest caps a year of drink-driving problems for young Hollywood, with Lindsay Lohan, Paris Hilton and Nicole Richie all serving jail time for DUI-related offences.
