Redmond O'Neal, the son of Ryan O'Neal and Farrah Fawcett, was arrested for heroin possession, People reports.
The 26-year-old, who's on felony probation, was pulled over Tuesday by Santa Monica, Calif., police for running a red light, during which officers found heroin and marijuana in the vehicle.

After police determined he was not under the influence at the time of his arrest, O'Neal was booked for the red light infraction, violating felony drug probation and possession of a controlled substance. He is being held without bail pending a court appearance Thursday. Because he was on felony probation, O'Neal could be sent back to prison.
