Two prison officers have been seriously injured in a riot at Mountjoy Prison in Dublin tonight.
The incident began at around 7pm when over 70 inmates barricaded themselves into the recreational yard in the prison armed with snooker cues and legs of tables.
As prison officers attempted to deal with the situation, two members of staff were injured and have since been taken to hospital.
Officers from other prisons were drafted in to deal with the situation and at around 9pm the public order unit was called in.
By 9:30pm, all of the prisoners were returned to their cells and order has been restored.
The Irish Prison Service said management was on site and the matter had been dealt with quickly.
