Paris Hilton has been arrested for drug possession after officers in Las Vegas stopped the car she was travelling in.

The American socialite was taken into Clark County Detention Centre this morning on a charge of possession of cocaine.
The 29-year-old was in a car driven by a friend when officers stopped the vehicle late last night.

Public Information officer Marcus Martin said officers pulled over the car after they noticed what they suspected to be marijuana smoke coming from it.

During the stop officers found what appeared to be a controlled substance on Hilton and tests showed it was cocaine, Mr Martin said.

It is not known how much of the drug was found, Mr Martin added.

Las Vegas police lieutenant Wayne Holman said the hotel heiress was still being held in custody.

Hilton left a message on her Twitter page just minutes before the news broke - but gave nothing away about her arrest.
"Going to bed. Sweet dreams everyone," she tweeted.
