CONCORD, N.H. (AP) — A New Hampshire man has been sentenced to more than four years in federal prison for methamphetamine trafficking.

Court documents say 45-year-old Peter Dauphin, of Laconia, sold meth five times last year to someone who was cooperating with law enforcement officers. The U.S. Attorney's office says all of the transactions took place at Dauphin's automotive repair shop in Gilford.

The case was investigated by police in Gilford and Laconia in conjunction with the FBI New Hampshire Safe Streets Gang Task Force.
