(AP) — A 39-year-old northeast Nebraska man has been sentenced to prison for ramming his tractor into a state trooper’s car.

Online court records say Aaron White, of Plainview, was sentenced on Wednesday in Antelope County District Court. He was given 25 to 30 years for assaulting an officer and 20 months to five years for criminal mischief. He’d pleaded no contest to both charges after prosecutors dropped two more counts of criminal mischief. The two sentences are to be served at the same time.

Authorities say White created several disturbances on Dec. 18, 2012, in Plainview. When law enforcement officers confronted him, White tried to ram a deputy’s car with his tractor before hitting a trooper’s car and hurting him.

Another officer shot White.
