A Pennsylvania man was arrested Wednesday on charges that he assaulted an Associated Press photographer and police officers during the Jan. 6 riot at the U.S. Capitol. Alan William Byerly, 54, was armed with what appeared to be a stun gun when he charged at officers guarding the Capitol, an FBI agent wrote in an affidavit. After police apparently removed the device from his hand, Byerly continued to charge at the officers, punching or pushing at least three of them, and tried to grab an officer’s baton.
