Action movie star Jan-Michael Vincent was sentenced to three years probation in Laguna Beach, Calif., on Wednesday after pleading guilty to three counts of public drunkenness. Vincent, 55, who found fame on TV’s “Airwolf” series, was also ordered to pay $800 in fines and undergo a 6-month alcohol treatment program. Vincent admitted to three instances of being drunk last March. He was found sleeping in a ditch in one incident, sitting on a curb in another and, in a third incident, pounding on neighbors’ front doors. At the time the actor was already on probation for drunk driving in 1996, when he crashed into the back of his girlfriend’s car.
