Redmond O'Neal, the son of actors Farrah Fawcett and Ryan O'Neal, was arrested again on Tuesday after police said they found heroin and marijuana inside his car.

It was the latest in a string of drug-related arrests for the 26 year-old O'Neal, whose mother died of cancer in 2009.

O'Neal was pulled over during a traffic stop in the California beach city of Santa Monica, after he ran a red light in his car, police said. Because he was still on probation for an earlier heroin possession conviction, he is being held without bail for alleged drug possession ahead of a court appearance on Thursday.

Last year, O'Neal completed a program designed to help users end their dependency on drugs that he had begun in 2009, when Fawcett was in the final stages of her battle against cancer.
