The fourth of four paramilitary bombings in the centre of Dublin takes place in Sackville Place on January 20, 1973.

The first bombing takes place in Burgh Quay on November 26, 1972. The next two bombings take place on December 1, 1972, in Eden Quay and Sackville Place. Three civilians are killed and 185 people are injured in the four bombings. No group has ever claimed responsibility for the attacks, and nobody has ever been charged in connection with the bombings.

On Saturday, January 20, 1973, at 3:08 p.m., a male caller with an English accent calls the telephone exchange in Exchequer Street, Dublin, with the following bomb warning: “Listen love, there is a bomb in O’Connell Street at the Bridge.” Although the call is placed from a coin box in the Dublin area, the exact location is never determined. The receiver of the call immediately contacts the Garda Síochána. The streets of central Dublin are more crowded than usual as Ireland is playing the All Blacks at an international rugby match being held that afternoon in Lansdowne Road.

At 3:18 p.m., a man leaving Kilmartin’s betting shop in Sackville Place notices smoke or steam emanating from the boot of a red Vauxhall Victor car parked outside Egan’s pub facing the direction of O’Connell Street. Its registration number was EOI 1229. About five seconds later the bomb inside the red car’s boot explodes, scattering sections of the vehicle and throwing the man off his feet. The explosion is so powerful that it hurls the car’s roof over adjacent Abbey Street where it lands in Harbour Place. The right-hand rear hub and axle sections are blasted through a metal grill on a shop window.

A CIÉ bus conductor, 21-year-old Thomas Douglas, originally from Stirling, Scotland, is passing the betting shop just as the bomb goes off and the force of the blast hurls him through a shop front window where he dies minutes later of shock and hemorrhage from the multiple injuries he received in the explosion. The entire shop front is devastated and spattered with blood. Fourteen people are badly injured in the bombing which causes bedlam as hysterical Saturday afternoon shoppers seek to flee the area in panic and confusion. The car bomb detonates at almost the exact location of the December 1 bomb. Later eyewitness accounts suggest that the car had been parked at the curb several hours before it exploded. According to journalists Jim Cusack and Henry McDonald in their book UVF: The Endgame (Poolbeg Press, 2008), the bomb is designed to cause widespread chaos and alarm throughout the city, and to inflict massive injuries upon shoppers and pedestrians as Saturday is traditionally the busiest shopping day of the week for Dubliners.

Suspicion initially falls on the Provisional Irish Republican Army (IRA) and other republican groups. Shortly afterwards, however the blame shifts to loyalist paramilitary organisations, in particular, the Ulster Volunteer Force (UVF). Gardaí receives a telephone call from a male caller in Belfast who gives the names of five men who he claims are responsible for January 20 car bombing. The caller says that the five men were originally from Belfast’s Sailortown area but had since relocated to new housing estates in the city. It is not known what action, if any, was ever undertaken by the Garda Síochána to follow up this telephone call. The UVF has never admitted responsibility for the bombing.

Irish Supreme Court Justice Henry Barron commissions an official inquiry into the four bombings. The findings are published in a report in November 2004. The Inquiry concludes that it “seemed more likely than not” that the bombing of the Film Centre Cinema on November 26, 1972, was “carried out by Republican subversives as a response to a Government ‘crackdown’ on the IRA and their associates” and to influence the outcome of the voting in the Dáil regarding the passage of the controversial amendment to the Offences Against the State Acts. Regarding December 1, 1972, and January 20, 1973, car bombings, the Inquiry concludes that confidential information obtained by the Gardaí indicates the three attacks were perpetrated by the UVF, “but no evidence was ever found to confirm this. Nor was there any evidence to suggest the involvement of members of the security forces in the attacks.”
