This briefing is Amnesty International’s investigation into Tiger Base, the Anti Kidnapping Unit of the Nigeria Police Imo state Command. It uncovers entrenched human rights violations, including prolonged arbitrary detention, torture, extortion, and enforced disappearances – including the removal of children from their mothers without records. Detainees are held in degrading conditions. Cells are overcrowded, poorly ventilated, and unsanitary – resulting in severe health complications and, in some cases, death. These practices violate Nigeria’s Constitution, the Anti Torture Act 2017, and international human rights law.
