Rioters cause thousands of pounds worth of damage in and around Dublin's Connell Street after H-Block meeting ends.
1,000 H-Block protesters attend a rally at the General Post Office (GPO) to hear speeches by relatives of the hunger strikers Theresa McCreesh (sister of Raymond McCreesh) and Elizabeth O'Hara (sister of Patsy O'Hara).
The meeting organisers appealed to the crowd to avoid violence when the event was over. When the protest march to Leinster House was diverted, demonstrators hurled petrol bombs at Gardaí outside British Home Stores Department Store. Gardaí baton charged the rioters in O'Connell Street.
A number of petrol bombs and paint tins were thrown at the Gardaí.
The violence caused damage to cars, shops and buses. 15 people were injured and 8 were arrested.
