Former child star Brian Bonsall was arrested in Colorado over the weekend after he allegedly hit his best friend in the face with a broken bar stool. The actor, 28, had been wanted by authorities since July 2008 on a year-old warrant for a separate assault.

Colorado Daily reports that Bonsall -- little Andy Keaton on 'Family Ties' -- was picked up at the home of his friend Micheal Trujillo Saturday night, where both had been drinking heavily and arguing loudly. According to the arrest report, Bonsall struck Trujillo with the splintered stool but remembers nothing.
