June 26, 1970
Riots broke out in Londonderry after mid-Ulster MP Bernadette Devlin was arrested. Devlin, who participated in the Bogside riots of 1969, was sentenced to six months in jail. She had previously applied for an appeal, which was rejected by the Northern Ireland Court of Appeals. When police attempted to arrest Devlin at a roadblock in Londonderry, violence quickly escalated with the use of petrol bombs to which soldiers responded with tear gas.
