According to Amnesty International: "On 10 August 2006, the police in Aba, Abia State, paraded 12 men labelled as “armed robbers” in front of the media. According to an official statement, four other suspects were killed “in a shoot-out” with the police during the arrests. The bodies of the 12 men were found at a mortuary a day later. The Nigerian government explained their deaths in a letter to the UN Special Rapporteur on extrajudicial, summary or arbitrary executions: “Upon sighting the police, the suspected robbery gang opened fire and police responded in self defence. During the fierce exchange of gunfire, three of the armed robbery suspects died on the spot while nine others sustained various degrees of injury from the shootout. Before they could be given medical attention, the remaining nine suspects, who survived the shootout died as a result of the injuries they sustained.” This explanation is unlikely as all 12 were paraded alive; some had gunshot injuries. To Amnesty International’s knowledge, no investigation was carried out into these deaths." ^[+]
