According to Amnesty International: "Usman Modu, a 26-year-old scrap metal dealer from Maiduguri, spent almost two and a half years in Giwa barracks. He was arrested in April 2012 in Gwange, Maiduguri, during a screening operation after a Boko Haram attack. All the people who left the mosque were gathered together: the elderly and children were allowed to go home. The men were brought before a “pointer”, who pointed at him and 17 other men. He was first taken to a JTF station called NEPA and then to Giwa Barracks. “One by one we were brought in front of an armoured tank. I never saw anything. People said there was someone inside. When I went up, soldiers said I should go left. They started beating me. One soldier beat me with his gun and I fell down. They tied my hands behind my back and beat me. Then told me to go inside the car. I don't know why I was chosen. I was surprised, I don't know what I have done.” The military released Usman with 41 others in November 2014. The 17 men arrested with Usman all died in military custody." ^[+]
