Chidi Nwagbo, a Nigerian migrant who had lived in the U.S. for 37 years, was detained at the Buffalo Federal Detention facility in Batavia on February 10, 2025, after attempting to cross into Canada. He arrived at the facility with frostbite and was under doctor's orders to see a specialist at Kessler Burn and Trauma Center in Rochester within a week. ICE staff never took him to the appointment. By the time he saw a doctor 16 days later, portions of six fingers had to be amputated due to untreated frostbite.
