On Tuesday, the agency released 11 new videos of suspects allegedly involved in violent clashes with law enforcement during the 6 January siege. Since January, the FBI has arrested more than 535 individuals for a variety of criminal activity on the day of the riot, but some of the most violent offenders have yet to be found, the agency said, including those caught on camera.
