DECEMBER 17--An “agitated” Internal Revenue Service employee was wearing a tin foil hat last week when Massachusetts cops confronted him for illegally possessing several firearms, according to a police report.

Acting on information provided by a Department of Homeland Security investigator, Tewksbury cops Tuesday afternoon pulled over a car driven by Roland Moore, a 46-year-old IRS customer service worker.

The federal agent had told police that he was investigating Moore, who had recently been “evaluated for possible mental health issues.” During conversations with IRS inspectors, Moore reportedly admitted to having guns in his Tewksbury home. A records check, however, showed that Moore’s firearms license had been suspended nearly six years earlier following an assault arrest.

As detailed in a Tewksbury Police Department report, when cops contacted Moore, he was “wearing a piece of tinfoil on his head under his cap” and he was “agitated” by the presence of law enforcement officers.
