A 22-year-old man faces aggravated domestic assault and other charges after allegedly attacking his girlfriend's car with a chain saw while she was in it. The woman was not injured, authorities said.

Vermont State Police said they got 911 calls at about 5 p.m. Thursday about a "male armed with a chain saw cutting into an occupied motor vehicle" in a convenience store parking lot near the junction of Vermont Routes 100 and 17.

Ellen Kryger, a deputy state's attorney in Washington County, said an unidentified bystander tried to intervene, but the alleged attacker, Brody R. Burke Jr. of Warren, hit him in the head.

Police said Burke fled but they tracked him down at the Hyde Away Restaurant in Fayston. When troopers approached, Burke kicked one in the chest and another in the leg, police said. He was taken to Central Vermont Medical Center in Berlin, where he engaged in "tumultuous behavior," spitting and screaming, Kryger said.

At his arraignment Friday in Vermont District Court in Barre, Burke pleaded innocent to the domestic assault charge, simple assault on the person who tried to intervene, two counts of assault on a police officer, unlawful mischief for damage to the vehicle, disorderly conduct and driving with a suspended license.

Burke was also arraigned on an earlier drunken driving charge and was jailed without bail on a charge that he had violated an earlier probation order.
