Actor RYAN O'NEAL was arrested at his Malibu, California home and booked on charges of assault with a deadly weapon and negligent discharge of a firearm after a fight with his son GRIFFIN on Saturday night (03FEB07). Sheriff's deputies and paramedics responded to a call at 12:30 am regarding a suspected battery and say that O'Neal, 65, fired at least one gunshot during the altercation. According to Los Angeles County Sheriff's Lt JOHN BENEDICT, "Deputies determined that Mr Griffin O'Neal was assaulted by his father during a family dispute." He was booked at the Lost Hills Sheriff's Station and released at 5:30 am on Saturday after posting $50,000 (GBP26,000) bail. Sheriff's sources tell entertainment website that a 22-year-old female friend of Griffin's was "inadvertently" injured at the scene and transported to a local hospital. Authorities would not confirm that the injury was a result of the gunshot. Griffin O'Neal, 42, the son of Ryan and JOANNA MOORE, has had brushes with the law before and spent 18 days in jail for failing to perform community service ordered by a judge who found him guilty of reckless boating in a 1986 accident that killed the son of film director Francis Ford Coppola. He also pleaded no contest to a drunken driving charge in 1989 and in 1992 agreed to spend one year in a live-in drug rehabilitation program after pleading no contest to charges he shot at his estranged girlfriend's unoccupied car. The latest incident occurred just one day after the family received the news that actress Farrah Fawcett, who was the longtime girlfriend of Ryan and the mother of Griffin's half-brother REDMOND, was cancer free after a battle with anal cancer.
