The Web site TMZ.com reported that Daniel Baldwin was arrested this week in Santa Monica, Calif., and booked on charges of grand theft auto and possessing illegal drugs.
The site said the owner of a 2003 GMC Yukon had reported via OnStar that his vehicle had been stolen. Police tracked the sport utility vehicle to a Santa Monica area hotel, where police witnessed Baldwin climbing into the vehicle.
Police said they found the narcotics and drug paraphernalia during a search of his hotel room.
Baldwin, 46, has already had two similar prior beefs with law enforcement this year. The brother of actors Alec, Stephen and William Baldwin, Daniel was released on bail Thursday.
