Ryan O'Neal and his son, Redmond, were arrested Wednesday at the actor's Malibu, Calif., home for alleged drug possession, a sheriff's spokesman confirms.

"This morning, deputies were doing a routine sweep to make sure Redmond was adhering to his probation," sheriff's spokesman Steve Whitmore said. "Upon searching the premises, the younger O'Neal was found in possession of narcotics. Later, a vial of drugs were found in the elder O'Neal's bedroom. We believe the drugs found were methamphetamines."

Both Ryan, 67, and Redmond, 23, were held at a local sheriff's station before both posted $10,000 bail each and were released from custody around noon.

Redmond O'Neal's mother is Farrah Fawcett and his half-sister is Tatum O'Neal, who was arrested July 1 in New York City for trying to buy drugs.

Reps for Ryan O'Neal and Farrah Fawcett weren't immediately available for comment.

Redmond has a history of drug abuse, having entered rehab in 2004 for heroin use. This past June, he pleaded guilty to drug possession and one misdemeanor DUI charge.
