According to Human Rights Watch: "Three witnesses described the detention of some 15 men on January 29, 2018 shortly after an ambush by armed Islamists killed two policemen on the road between the villages of Baraboulé and Petegoli. Two of the detained men, one with a mental illness, died as a result of mistreatment meted out by both policemen and soldiers. One witness described the man’s injuries: “he had black and blue marks and coagulated blood all over his body; and his face was visibly swollen.” Another witness said: The ambush happened around 6:30 a.m. The police asked for army reinforcement then started arresting shepherds who were watching their animals or going to market. I saw the police and soldiers beating them, severely, with wood, rubber cords and gun butts near the ambush site and on the way to the Djibo police station They insulted and threatened to kill them. Many were bleeding from gashes on their heads, arms and backs. They didn’t eat or drink for two days. On around day four of their detention, they were taken out of the cell to have their photographs taken, but one detainee, who was mentally ill, didn’t understand what was being asked of him; he resisted holding up the paper for the police photo. The policemen set upon him until he fell down, and continued to beat and kick him. After seeing how bad off he was, the policemen took him to the clinic, but he died shortly thereafter. A second man, who had been detained near the ambush site in Petagoli, died in the cell…the prisoners yelled, ‘this man is sick…he’s going to die, he needs water!’ But a policeman said, ‘forget it, you’re all going to die here.’ The prisoner gave up his soul (died) an hour later." ^[+]
