AUGUSTA — A York man who pulled a knife on an off-duty state police trooper after running his car off the road pleaded guilty Monday to assaulting an officer and three other charges related to the incident Feb. 7 in Manchester.

Jerry Larrivee III, 48, was sentenced in Kennebec County Superior Court to five years in jail with all but 11 months suspended and two years of probation. He also got a five-year sentence, all suspended, and two years of probation to be served after the first sentence.

Larrivee was charged with assaulting an officer, driving after habitual-offender revocation, drunken driving and refusing to submit to arrest or detention.

According to police reports, Larrivee was driving north on Pond Road when he hit the trooper’s personal vehicle.  Jonathan Leach followed him and identified himself to Larrivee as a trooper. Larrivee then tried to pull a knife on Leach, who subdued him until other officers arrived.
