Ligia Garcia, an asylum-seeker from Colombia with no criminal record, was arrested by ICE on July 31, 2025, after attending her immigration court hearing in San Francisco and detained at the ICE field office at 630 Sansome Street. She was held in harsh conditions including small, cold rooms with no beds, forced to sleep on the floor under bright lights, limited hygiene supplies, and restricted access to counsel after 3 p.m. and on weekends. She was held for extended periods despite the holding cells being designed for stays under 12 hours. On September 18, 2025, the ACLU and immigrant rights lawyers filed a class-action lawsuit on behalf of Garcia and three other plaintiffs detained at the same facility, challenging ICE's detention practices and courthouse arrest policies and alleging unconstitutional conditions and violations of due-process protections.
