Former "Family Ties" actor Brian Bonsall has been arrested again in Colorado, this time on a charge of using marijuana in violation of the terms of his release.

Deputies handcuffed and led the 28-year-old from a Boulder courtroom Friday after he pleaded not guilty to an assault charge and a failure to report charge involving another case. Bail was set at $10,000.

Bonsall's defense attorney says the actor needs marijuana for headaches and has applied for a medical marijuana card through the state.

He is accused of repeatedly hitting a friend in the head with a broken wooden stool in December and of missing a court hearing in 2007 in another assault case.

Bonsall played the role of the youngest Keaton sibling, Andy, on the NBC sitcom starring Michael J. Fox.
