Peter Francis Stager became the suspect after a video of the attack appeared on Twitter and someone recognized him and reported him, according to the federal criminal complaint against him obtained by PEOPLE. The video shows Stager holding an American flag and using "the pole to repeatedly strike [an officer] while on the steps of the U.S. Capitol building," the complaint states.

Death is the only remedy for what's in that building," referring to the Congressmen and Senators inside the Capitol, according to the complaint. Stager was arrested Thursday night, the Arkansas Times reports. According to the complaint, Stager allegedly told an associate of his that he didn't know the man he was attacking was a police officer, and that he'd been under the impression the person he was striking was a member of Antifa. However, the complaint notes that the officer's uniform had "Metropolitan Police" clearly written across the back. Want to keep up with the latest crime coverage?
