TMZ has obtained the mugshot of actor Ryan O'Neal, who was arrested Saturday morning at his Malibu home. He was booked on charges of assault with a deadly weapon and negligent discharge of a firearm after a fight with his son, Griffin. O'Neal was released after posting $50,000 bail.

Police tell TMZ that O'Neal, 65, fired at least one gunshot during the scuffle.

Cops say he was booked at the Lost Hills Sheriff's station without incident. He was released at 5:30 AM.

Sheriff's sources tell TMZ that a 22-year-old female friend of Griffin's was "inadvertently" injured at the scene and transported to a local hospital. Sources wouldn't confirm if the injury was a result of the gunshot.
