Seven prison officers from Mountjoy were taken to the Mater Hospital following a disturbance in the prison this afternoon. It is understood that a fight broke out between two prisoners in the main prison at around lunchtime. Other prisoners then joined in before a number of prison officers intervened and order was restored. The injured officers were taken to Hospital but were later discharged. The Prison Officers Association said that they were awaiting a report from the officers involved, but they said they would be carrying out their own investigation into the incident.
