At Leeson Street, roughly halfway between the clashes at Springfield and Hastings Street RUC police stations, an RUC Humber armoured car was attacked with a hand grenade and rifle fire. At the time, it was not known who had launched the attack, but it has since emerged that it was IRA members, acting under the orders of Billy McMillen. McMillen also authorised members of the Fianna (IRA youth wing) to attack the Springfield Road RUC police station with petrol bombs. Shots were exchanged there between the IRA and RUC.
