Former Boston Police K-9 Officer Arrested and Charged with Assaulting a Law Enforcement Officer During Jan. 6 Capitol Riot

A former Boston Police K-9 officer was arrested on Thursday for his alleged role in the Jan. 6 attack on the U.S. Capitol. Joseph Fisher, 52, was taken into custody by the FBI and charged with a litany of offenses, including a felony charge of assaulting a law enforcement officer.

According to court records, Fisher was captured on video assaulting an officer as police worked to move back the mob ignited by former President Donald Trump. The U.S. Capitol Police officer was chasing after a rioter who had used a “chemical irritant” on police when Fisher allegedly pushed a chair into the officer.

Fisher faces several counts, including felony charges of obstruction of law enforcement during civil disorder and assaulting, resisting, or impeding certain officers. A current Boston Police officer who knows Fisher positively identified Fisher after online sleuths helped track him down, according to the FBI.

The Jan. 6 attack on the Capitol left five people dead and dozens of officers injured. The FBI has since been investigating the incident and has arrested more than 300 people in connection with the riot.

Fisher is the latest to be charged in connection with the attack. He is currently being held in federal custody and is awaiting trial. If convicted, he could face up to 20 years in prison.
