"FAMILY TIES"....

Brian Bonsall, who played the youngest, blondest Keaton on 80s sitcom "Family Ties," was sentenced to two years probation in relation to a March assault incident.

Bonsall was arrested in Boulder, Colorado, after his girlfriend told police he poured an alcoholic drink on her while she slept, put her in a choke hold, and threw her onto a bed. Bonsall counterclaimed that he pushed her in self-defense after she cut his arm and face with a steak knife.
