PORTLAND — A Durham man admitted Wednesday to having a gun after he was barred from doing so due to an earlier domestic violence conviction.

Richard Leblond, 51, pleaded guilty in U.S. District Court to a charge of possession of a firearm by a prohibited person, a felony punishable by up to 15 years in prison and a fine of up to $250,000.

A deputy from the Androscoggin County Sheriff’s Office served Leblond with a temporary protection from abuse order at his home in Durham on April 9, according to prosecutors.

As part of the order, Leblond was required to hand over any guns in his possession.

Leblond told the deputy that he had several guns and OK’d a search of his home, prosecutors said.

During the search, investigators found more than a dozen handguns, pistols, rifles and shotguns, all of which were recovered from two gun safes inside Leblond’s  home, prosecutors said.

Because Leblond had been convicted in 2009 in Lewiston of misdemeanor domestic violence charges, he wasn’t legally allowed to have any guns.

No sentencing date has been set.
