Luis Hernández, a 38-year-old Nicaraguan migrant who marched in Nicaragua's 2018 pro-democracy protests, had been denied asylum but granted protection from deportation under the Convention Against Torture. He was detained at a routine immigration check-in in February and taken to a Texas tarmac on Aug. 28, where he says he was struck twice in the back and once in the knee with pepper-spray canisters and was never notified he would be sent to Africa. He told the Los Angeles Times he went days without eating or sleeping after arriving in Bangui, where he was housed in a complex monitored by armed guards.
