A B-movie actor who appeared in a flop US remake of a popular British sitcom rioted at the Capitol on January 6 and was filmed saying: 'Hey Nancy, go f**k yourself,' investigators say. 

Michael Aaron Carico, 33, was arrested on August 11 in Burbank, California after the FBI then identified him as the man in a 30-second video saying: 'Hey Nancy, go f*** yourself.' 

Carico - whose biggest role was in the unsuccessful US remake of The Inbetweeners, a cult British comedy sitcom, has now been charged with entering a restricted building; parading, demonstrating or picketing in a Capitol building; and disorderly conduct, after an informant told the FBI he boasted about being there.

According to charging documents, Carico was busted thanks to an informant who told investigators that the actor had been bragging about his participation.

When another person asked that unidentified informant how he could find the bragger on Facebook, the informant said, Caracio replied 'michaelaaroncaracio.'

She said she wrote down his name to look it up later.

Investigators with the FBI then tracked down Carico's personal Instagram page, and saw that he appeared to match the person seen in several videos from the riots, when he allegedly wore a camouflage shirt with brown and black gloves. 

They obtained a search warrant for data from the performer's Google account and say they found photos and videos taken during the assault showing.

Those are said to show Carico in the same outfit in the D.C. metro area, and climbing the ladder to the top of the media tower at the Capitol.
