According to Human Rights Watch: "According to witnesses, many of the public executions in July 2009 by the police occurred at their headquarters in Maiduguri. Human Rights Watch documented 28 alleged extrajudicial killings committed by the police between July 28 and August 1, 2009, in Maiduguri. Twenty-four of them took place outside the front gate or inside the compound of the police headquarters. [snip] A 24-year-old woman recounted seeing mobile police officers execute 16 detainees at police headquarters on July 28 and 29. On the first day’s shootings she stood at the fence of the headquarters, along with others, and saw a Police Mobile Force (MOPOL) officer order the execution of 10 men: There was a big [heavyset] MOPOL [officer] there. I don’t know his rank. He was saying in Hausa, “Shoot them all. What are you waiting for?” Three MOPOLs did the shooting. Some of those killed wore kaftans with camouflage. They yelled “Allahu Akbar,” and the police would know they were Boko Haram and shoot them. Others denied they were Boko Haram members. One of them was crying.... But the police pushed them aside and shot them." ^[+]
