Paris Hilton in Vegas Coke Bust

Socialite Paris Hilton was arrested late Friday night in Las Vegas after cocaine was found in her purse. She was released from jail Saturday morning.

According to People, which cited a police spokesman, police pulled over a vehicle carrying the Hilton hotel heiress on Las Vegas Boulevard. The male driver was arrested on DUI charges.

"Public Information officer Marcus Martin said the vehicle was stopped after officers believed marijuana smoke was coming out of the car in front of the Wynn Hotel, where Hilton's boyfriend, Cy Waits, operates a nightclub," reported People.

Police found cocaine in Hilton's purse and took her to the local detention center before her Saturday morning release. It was her third drug-related incident this summer, with the other two involving marijuana.
