A former Boston police officer was arrested Thursday on charges that he assaulted a police officer after storming the US Capitol with the mob of President Donald Trump supporters on January 6, 2021. Joseph Robert Fisher is accused of pushing a chair into a Capitol police officer inside the building as the officer was running after another rioter who deployed pepper spray, according to court documents. Moments later, Fisher also ”engaged in a physical assault” against the officer, which ended with Fisher on the ground, an FBI agent wrote in the court papers. A current Boston police officer helped investigators identify Fisher in photographs, the agent wrote.
