Federal authorities are continuing to pursue some of the most violent rioters who participated in the deadly Capitol assault six months after supporters of former President Donald Trump clashed with law enforcement authorities in a failed attempt to halt the certification of President Joe Biden’s election.

The FBI released 11 new videos Tuesday showing suspects–some of them engaged in hand-to-hand combat with police as the government marked a new milestone in what has become the largest criminal investigation in U.S. history.

Since January, at least 535 people have been arrested, including 165 who have been charged with assaulting, resisting or interfering with police who battled rioters for hours on defensive lines
