That cute little kid from Family Ties, Brian Bonsall was arrested in Boulder, CO on Saturday, after he allegedly beat his friend Michael Trujillo in the face with a broken bar stool.

Micahel told police at the scene that he and Brian got into an argument, and that he kindly asked Brian to leave his apartment. Instead of complying, Brian took a stool, and assaulted Michael with it. Brian told police that he was drunk and possibly on drugs, and didn’t remember what happened.

He’s currently being held on a third-degree assault charge, and a failure to appear charge in connection with a 2007 assault case involving his girlfriend. His two bonds were set at a total of $7,500.
