Sheriff's spokesman Steve Whitmore says Redmond O'Neal was arrested Sunday on suspicion of bringing narcotics into a jail facility after admitting he was carrying drugs. He is being held on $25,000 bail.
Whitmore says a deputy stopped O'Neal, who was at the jail giving a ride to a friend.
O'Neal was arrested in September with Ryan O'Neal and charged with felony methamphetamine possession. He was on probation for a previous drug conviction.
A phone message left for his attorney wasn't immediately returned.
The arrest was first reported by RadarOnline.com.
