A federal appeals court panel on Thursday moved to stay a district judge’s order that cleared the release of an alleged leader of a white supremacist organization who had previously fled the U.S. to evade prosecution.

Robert Rundo, the alleged leader of the white supremacist ‘Rise Above Movement,’ was released from prison in Orange County Wednesday, before the 9th Circuit Court of Appeals issued their temporary stay. The U.S. Attorney’s Office in the Central District of California confirmed Thursday night that Rundo had been taken into custody.

“Rundo was released from custody at some point yesterday evening. As you may have seen, we petitioned the 9th Circuit Court of Appeals to stay the release order, which was granted this morning. Rundo was taken into custody this evening by the FBI,” read a statement from the office.

U.S. District Judge Cormac J. Carney had earlier dismissed charges against Rundo and a co-defendant, Robert Boman, both of whom were charged in 2018 with conspiracy to violate the Anti-Riot Act, and rioting, for their role in alleged attacks on counter-protesters at political rallies in 2017.
