Concord — A 27-year-old North Haverhill man has pleaded guilty in federal court to two counts of being a felon in possession of a firearm, according to a U.S. Department of Justice news release issued this week.

Thomas S. Harris sold a shotgun and a rifle to a pawn shop in Libson, N.H., in August and September 2016. Because Harris is a felon, he can’t possess firearms.

He is slated to be sentenced in U.S. District Court in Concord on Sept. 4, the release states.
