PORTLAND (AP) – A 46-year-old man has been sentenced to 46 months in prison for hitting and kicking his girlfriend and slamming her head into a car window so hard that it shattered.

Albert Smith of Rochester, N.H., was sentenced Tuesday in U.S. District Court in Portland, Maine.

According to the U.S. attorney’s office, Smith and his girlfriend were at the Indian River Campground in Eliot, Maine, last August when Smith forced her to New Hampshire and back into Maine while he assaulted her repeatedly and slammed her head into the driver’s side window.

He was convicted of interstate domestic violence.
