A key participant in the January 6, 2021, Capitol riot has been apprehended in South Dakota, according to the FBI. The man, William George Knight, faces a multitude of charges in connection with the Capitol attack, which includes felony counts of assault of a federal officer and obstruction of law enforcement in a civil disorder.

The FBI’s affidavit vividly depicts Knight’s involvement in the riot. Video evidence compiled by “sedition hunters” shows him as one of the first to breach the initial barriers, actively ripping away police barricades as the mob confronted law enforcement. Eyewitness accounts and footage further depict Knight aggressively engaging with officers, at one point rushing toward the police line with an extended flagpole, only to then smash it against the concrete.

Online sleuths had previously dubbed Knight the “Dreaded Proud Boy” due to his distinctive blond dreadlocks and proximity to members of the far-right organization in the initial Capitol breach.
