Socialite detained at traffic stop in Las Vegas

Paris Hilton was arrested in Las Vegas on Friday night and charged with cocaine possession. She was released early Saturday.

Hilton, 29, was arrested after a traffic stop by police in which an undisclosed amount of cocaine was allegedly found in her purse.

Hilton was a passenger in the car; the unidentified driver was charged with driving under the influence.

She spent three weeks in a Los Angeles jail in 2007 for violating her probation in an earlier reckless driving charge.
