Redmond O’Neal, the son of actor Ryan O’Neal and the late actress Farrah Fawcett, was arrested Aug. 2 for allegedly possessing illegal drugs following a traffic stop in Santa Monica, police said.

O’Neal, 26, who was driving a black 2010 Nissan Altima, was stopped by police after he allegedly failed to stop for a red traffic signal while turning onto Olympic Boulevard from northbound Lincoln Boulevard in Santa Monica at about 8:15 a.m., Sgt. Richard Lewis said.

During the traffic stop, O’Neal told officers that he was on probation, which police confirmed through records, Lewis said. The driver then consented to a search of his vehicle and officers allegedly found heroin and marijuana inside, Lewis said.

O’Neal was arrested and transported to the Santa Monica Jail where he was booked for felony possession of a controlled substance, possession of marijuana in a vehicle, a red traffic light violation and probation violation, police said.

He was being held without bail at the Santa Monica Jail pending arraignment.
