Operation Demetrius was a British Army operation in Northern Ireland on 9–10 August 1971, during The Troubles. It involved the mass arrest and internment (without trial) of people suspected of being involved with Irish republican paramilitaries. Armed soldiers launched dawn raids throughout Northern Ireland, sparking four days of rioting that killed 20 civilians, two IRA members and two British soldiers. About 7,000 people fled their homes, of which roughly 2,500 fled south of the border.
