Balcombe Street siege

The Balcombe Street siege was an incident involving members of the Provisional Irish Republican Army (IRA) and the Metropolitan Police Service of London lasting from 6 to 12 December 1975. The siege ended with the surrender of the four IRA paramilitaries and the release of their two hostages. The events were televised and watched by millions.

In 1974 and 1975, London was subjected to a 14-month campaign of gun and bomb attacks by the Provisional IRA. Some 40 bombs exploded in London, killing 35 people and injuring many more. In one incident the Guinness Book of Records co-founder and conservative political activist Ross McWhirter was assassinated; he had offered a £50,000 reward to anyone willing to inform the security forces of IRA activity.

The four members of what became known as the "Balcombe Street gang" – Martin O'Connell, Edward Butler, Harry Duggan and Hugh Doherty – were part of a six-man IRA Active Service Unit (ASU) that also included Brendan Dowd and Liam Quinn. Quinn had recently shot dead police constable Stephen Tibble in London after fleeing from police officers. The flat he was seen fleeing from was discovered to be a bomb factory used by the unit.

The Balcombe Street siege started after a chase through London, as the Metropolitan Police pursued Doherty, O'Connell, Butler and Duggan through the streets after they had fired gunshots through the window of Scott's restaurant in Mount Street, Mayfair. They had thrown a bomb through the restaurant window a few weeks before on 12 November 1975, killing one person and injuring 15 others. The Metropolitan Police Bomb Squad had detected a pattern of behaviour in the ASU, determining that they had a habit of attacking again some of the sites they had previously attacked. In a scheme devised by a young detective sergeant, the Met flooded the streets of London with unarmed plain-clothes officers on the lookout for the ASU. The four IRA men were spotted as they slowed to a halt outside Scotts and fired from their stolen car.
