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.
