Brain Bonsall
Brain Bonsall has been charged with second-degree assault after his arrest last weekend.
The Family Ties actor allegedly attacking a pal with a broken bar stool.
The former child star allegedly beat Michael Trujillo in the face with a splintered chair during a night of heavy drinking at his friend's Colorado home.
Concerned local residents called authorities, Bonsall was booked at the scene, and then cops to realise he had been wanted for more than a year after missing a court hearing in 2008.
Bonsall has allegedly violated terms of his probation stemming from an assault on his girlfriend in 2007.
The actor is best known for playing Michael J. Fox's little brother on the hit '80s sitcom.
He is currently being held in Boulder County Jail on $7,500 (£4,687) bail, and if convicted of assault he faces up to six years behind bars.
