Twenty-six immigrant fathers and sons have sued The GEO Group, which runs immigration detention centers for the federal government, alleging that armed men swarmed their rooms in a Texas-based detention center and used excessive force to separate them, in violation of a nationwide preliminary injunction against family separations.

The plaintiffs are 13 fathers and their 13 sons, ranging in age from 6 to 17, who sought asylum in the U.S. after fleeing persecution and violence in their home countries of Honduras, Guatemala and Brazil. They were separated for weeks or months last year under the Trump administration’s “zero tolerance” policy, but then reunited after a California federal court issued a preliminary injunction to stop family separations, and order the reunification of immigrant parents and children.
