Advocates took action on two fronts Wednesday to push for better treatment of immigrants in federal custody, claiming they are having their belongings taken by U.S. agents and are languishing behind bars because of unfair bond conditions set by judges and others.

The American Civil Liberties Union of New Mexico and other organizations filed an administrative complaint with the Department of Homeland Security alleging that Border Patrol agents have been seizing immigrants’ property before deporting them to Mexico, in some cases to cities where they didn’t know anyone.
