Campaigners in Nigeria have responded with scepticism to the announcement that a police unit, widely accused of brutality, has been disbanded. BBC Africa reports that protesters had called for the Special Anti-Robbery Squad, or Sars, to be broken up. But they’re unhappy that its officers are being redeployed to other units rather than being disciplined. In a statement, Nigeria’s police chief said allegations of abuse would be investigated. Demonstrations against the squad spread to Europe and Canada following widespread reports of unlawful arrests, torture and even deadly shootings.
