Nigeria inquiry: 33 detainee deaths were 'entirely preventable'

An inquiry into the deaths of 33 detainees in Minna, Nigeria, found they died from acute respiratory failure caused by severe overcrowding, poor ventilation and officers ignoring distress calls. Fifty people were held in a cell of about 20 sq m on suspicion of illegal mining at sites that were licensed. Implicated officers face suspension and legal action.
