Martin Hernandez-Torres, a noncitizen who has lived in the United States for 30 years and has cancer, was arrested Wednesday during a "reasonable fear" interview at the ICE field office at 630 Sansome Street in San Francisco. He was held in harsh conditions including small, cold rooms with no beds, forced to sleep on metal benches or the floor with only thin plastic or foil as blankets, bright lights kept on all night causing sleep deprivation, open toilets, limited hygiene supplies, and restricted access to counsel and medical care. He was held for extended periods—sometimes up to six days—despite the holding cells being designed for stays under 12 hours. The ACLU, alongside the Lawyer's Committee for Civil Rights and CARECEN, filed a class-action lawsuit on September 18, 2025, on behalf of Hernandez-Torres and three other asylum-seeker plaintiffs, challenging ICE's detention practices and courthouse arrest policies and alleging unconstitutional conditions and violations of due-process protections.
