Officials in northern Brazil say a four-day riot at a notoriously violent prison has ended peacefully. More than a thousand inmates of the jail in the Amazonian state of Rondonia used their own relatives as hostages in a protest against the transfer of a gang leader and against poor living conditions. After 4 days inside one of Brazil’s most dangerous jails, all the hostages left unharmed; It seems the group, many of whom were children of inmates, were successfully and perhaps willingly used as a bargaining chip for the prisoners to get what they wanted. The inmates’ key demand was that the notorious convicted murderer Edinildo de Souza be allowed to complete his 30year sentence with them in the Urso Branco prison rather than anywhere else. Only once a handcuffed Mr. de Souza was returned to the jail were the hostages released.
