Nicolas Cage‘s 20-year-old son Weston Cage was arrested following a violent altercation at a restaurant. He was at The Farmer’s Kitchen in Hollywood just after 4:00 p.m. Tuesday when he flew into a rage and began attacking his trainer when he was told he couldn’t eat a certain item on the menu. The trainer was able to hold Weston down, and another person tried to help to calm him, but Weston continued to “freak out,” according to onlookers. When police arrived, they threatened to taser him if he didn’t get on the ground and lie quietly. Weston complied and was handcuffed, strapped to a gurney and taken to Cedars-Sinai Medical Center for a mental evaluation and a possible 5150 psychiatric hold. When asked, restaurant workers said he appeared to be under the influence of drugs or alcohol at the time of the altercation. Weston reportedly had a stormy argument with his wife of two months, Nikki Williams, which may have had led to his behavior later in the day. Weston is Nicolas’ son with former girlfriend Christina Fulton. The elder Cage arrived at the hospital yesterday evening and according to sources, has cleared his schedule so he can stay near his son.
