A federal grand jury indicted nine suspected North Texas “antifa cell” operatives in connection with the July 4 attack on a U.S. Immigration and Customs Enforcement detention center in Alvarado, the Acting United States Attorney for the Northern District of Texas Nancy E. Larson said in a news release Friday.

Seven others were “charged by information” with offenses ranging from using weapons and explosives to attempted murder.

On July 4, Alvarado police officers were dispatched to the detention center in the 1200 block of Sunflower Lane around 10:56 p.m. after reports of a suspicious person, The News previously reported.

According to the release, multiple masked individuals dressed in black, some armed, vandalized security cameras and vehicles in the Prairieland ICE Detention Center parking lot.
