Hollywood actor Ryan O'Neal and his son, Redmond, were formally charged on Thursday with possession of methamphetamine and other drug offenses stemming from a search of their home last month.

The 67-year-old actor and his son, 23, were arrested together on Sept. 17 after police conducted a sweep of their Malibu home under the terms of Redmond O'Neal's probation for an earlier drug possession case.

Police found methamphetamine in the father's bedroom as well as in his son's possession, said Jane Robison, a spokeswoman for the Los Angeles County District Attorney's Office.

Both men were charged with felony possession of methamphetamine, and the son was additionally charged with lesser counts of possessing drug paraphernalia and illegal possession of pepper spray.

Felony drug possession carries a possible maximum sentence of three years in prison, but neither man is likely do any time behind bars if convicted.

Because the elder O'Neal, an Oscar nominee for his 1970 role in "Love Story," has no previous record, he would probably be placed in a drug rehabilitation program, Robison said. His son, too, would likely see his court-ordered rehab extended.

Redmond O'Neal, the son of actress Farrah Fawcett, pleaded guilty in June to possessing heroin and methamphetamine and driving under the influence, and was placed on three years' probation. In a court appearance on Oct. 8, he admitted to a relapse and was ordered to undergo two weeks of treatment.

Both men are due in court on Nov. 13 to enter pleas in connection with the latest case. Ryan O'Neal's agent was not immediately available for comment.

Ryan O'Neal first came to fame on the 1960s prime-time soap opera "Peyton Place" and more recently has appeared in the Fox network drama "Bones."

Daughter Tatum O'Neal, 44, a former child actress who won an Oscar for her role opposite her father in the 1973 film "Paper Moon," pleaded guilty in July to disorderly conduct stemming from a drug arrest.
