A year after graduating from an intensive, court-ordered drug program, Redmond O'Neal was arrested for investigation of drug possession Tuesday by Santa Monica police during a traffic stop.
"After Mr. O'Neal admitted to being on felony probation and consented to a search, the officers found heroin and marijuana in the vehicle," Sgt. Richard Lewis tells PEOPLE.
O'Neal, who was not determined to be under the influence of drugs, was booked and held without bail pending a court appearance Thursday.
O'Neal, 26, the troubled son of actors Ryan O'Neal and the late Farrah Fawcett, said last year he planned to stay clean and sober
after serving time for various drug-related arrests and then attending Los Angeles's drug-court program.
Because he was on felony probation, O'Neal could be sent back to prison.
