Carmen Aracely Pablo Sequen, an asylum-seeker, was detained at the ICE field office at 630 Sansome Street in San Francisco and held in harsh conditions including small, cold rooms with no beds, limited hygiene supplies, and restricted access to counsel. She was held for extended periods—sometimes up to six days—despite the holding cells being designed for stays under 12 hours. The ACLU filed a class-action lawsuit on September 18, 2025, challenging ICE's detention practices and courthouse arrest policies, alleging unconstitutional conditions and violations of due-process protections.
