Hollywood actor Ryan O'Neal has been arrested in California for allegedly assaulting his son Griffin.
Ryan O'Neal was bailed after five hours in detention
The star was arrested on suspicion of assault with a deadly weapon and negligent discharge of a firearm after police were called to his Malibu home.
The 65-year-old actor was freed on bail after five hours in detention over what police called a "family dispute".
Ryan O'Neal found fame in 1960s US soap Peyton Place and went on to star in films like Love Story and Paper Moon.
Griffin O'Neal, 42, was not hurt in the incident although a 22-year-old woman suffered injuries that were not gun-related.
Police said they had not yet determined how many shots were fired from the handgun.
Ryan O'Neal and Farah Fawcett had a 15-year relationship
Mr O'Neal's manager Neil Hassman claimed the actor was defending himself after his son began "wildly swinging a fireplace poker".
The dispute came after Ryan O'Neal, actress Farrah Fawcett and some friends returned from dinner to celebrate her birthday, Mr Hassman said in a statement to showbusiness programme The Insider.
"It is unfortunate that what should have been an internal family disagreement was escalated to the point that Ryan felt he had to defend himself from Griffin's aggressive, extremely menacing physical behaviour," he said.
Ryan O'Neal, who was diagnosed with "non-life-threatening" leukaemia in 2001, had a 15-year relationship - and a son, Redmond - with Fawcett.
Griffin, whose own acting career never took off, is Ryan O'Neal's son from his first marriage, with Joanna Moore. His sister is Tatum O'Neal.
He was given an 18-day jail sentence for not performing 400 hours of community service after being found guilty of reckless boating in a 1986 accident that killed director Francis Ford Coppola's son Gian-Carlo Coppola.
In 1989, he also pleaded no contest to a drunken driving charge and was sentenced to probation.
And in 1992, he pleaded no contest to charges that he shot at his estranged girlfriend's unoccupied car.
At the time, he agreed to spend a year in a drug rehabilitation programme and serve five years on probation.
