BANGOR — Federal prosecutors say a 32-year-old Augusta man was sentenced to four years in prison for his role in conspiracy to steal mail.

U.S. Attorney Thomas E. Delahanty II says Ryan Pomerleau will also face three years of supervised release and must pay nearly $88,000 in restitution. Pomerleau pleaded guilty to conspiring to steal mail and theft of mail in January. A judge sentenced him on Monday.

Court records say Pomerleau stole mail, altered checks taken from mail and enlisted others to cash the altered checks at Augusta area banks. Investigators used a search warrant at a Seabrook, New Hampshire, hotel room to seize counterfeit checks, typewriters, tools and other evidence linked to Pomerleau.

The U.S. Postal Inspection Service and several local police departments conducted the investigation.
