A former Boston police officer pleaded guilty Thursday to entering the U.S. Capitol and assaulting an officer during the Jan. 6, 2021, insurrection, federal prosecutors said.

Plymouth resident Joseph Robert Fisher, 52, was arrested last March and indicted in September on eight criminal charges, including assaulting, resisting, or impeding certain officers and engaging in physical violence in restricted grounds or buildings.

Fisher is scheduled for sentencing on May 24, the U.S. Attorney’s Office for the District of Columbia said in a press release.

He joined the Boston Police Department in 1994 and retired on Dec. 14, 2016, The Boston Globe previously reported. Fisher spent his last several months on the force assigned to the “Medically Incapacitated Section,” according to the Globe.

Court documents indicate that Fisher stormed the Capitol with a mob of Donald Trump’s supporters as Congress was certifying President Joe Biden’s electoral victory.

Fisher was in the Capitol Visitor Center’s Orientation Lobby around 2:38 p.m. when a fight broke out between a U.S. Capitol police officer and other rioters.

“As a U.S. Capitol Police Officer pursued a rioter who had deployed pepper spray, Fisher pushed a chair into the Capitol Police Officer,” the DC U.S. Attorney’s Office said in March. Fisher then physically fought with the officer before leaving the Capitol.

According to court documents, Fisher’s hat — adorned with several Boston sports teams’ logos — helped investigators identify him in photos and video.
