Police say a New Hampshire man was arrested Wednesday night after he attempted to enter an Arlington home posing as an FBI agent, carrying a gun and restraints.

Gannon Kemper LeBlanc, 23, of Nashua is facing multiple charges including impersonating a police officer, carrying a firearm without a license, and unlawful possession of ammunition, according to Arlington police. He is being held without bail pending his arraignment Thursday in Cambridge District Court.

Police said officers received a report of a suspicious person at about 7 p.m. when they were informed the suspect, later identified as LeBlanc, was wearing a black suit and tie, black backpack, and a black hat with “FBI” lettering.


The residents of the home LeBlanc was allegedly trying to enter refused to let him in and immediately called 911. Officers located LeBlanc at the bus stop of Lee Terrance and Massachusetts Avenue, where he was arrested, police said.

During the ensuing investigation, officers discovered a stun gun and handgun, as well as leather gloves, duct tape, a ski mask, and copies of an FBI flyer that was given to the Lee Terrace residents, according to police.

Arlington Police Chief Frederick Ryan said in a statement that investigators do not believe the incident was a random act.

“The residents may have been targeted by the suspect, and we do not believe that the community as a whole was in danger,” he said.

Federal law enforcement agencies are assisting police with the ongoing investigation.
