A former governor of Mountjoy Prison said there is a sense that the system has failed when a prisoner is killed in an attack.
John Lonergan, who was governor of Mountjoy, in Dublin, for more than two decades, said a prisoner’s death can lower morale and is upsetting for staff and prisoners.
He was speaking after Robert O’Connor, 34, was attacked and fatally injured in Mountjoy Prison on Friday.
