A 43-year-old northeast Nebraska man has been given 18 months in prison for stomping on the head of a teenage girl.

A news release from the office of U.S. Attorney Deborah Gilg says Charles Phillips Jr., of Macy, was convicted of assault on a child resulting in substantial bodily injuries.

Phillips must serve three years of supervised release after he leaves federal custody and must pay restitution of nearly $1,200.

Gilg's office says Phillips got into an argument with his girlfriend on April 2 last year. When the girlfriend's 13-year-old daughter yelled at Phillips to leave her mother alone, Phillips cursed the girl and stomped on her head.

Gilg's office says the girl was knocked unconscious briefly and her nose was broken.
