Keith and Kenneth Littlejohn, self-proclaimed British Government spies, escape from Mountjoy Prison, a top-security prison in Dublin, on March 11, 1974, where they are serving sentences for armed robbery. It is another embarrassment for the authorities at the prison coming just five months after a helicopter plucked three leading Irish Republican Army (IRA) volunteers from the prison’s exercise yard.

The Littlejohn brothers are jailed on August 3, 1973, for a £67,000 robbery at an Allied Irish Banks branch on Grafton Street, Dublin, in October 1972, the biggest to date in Irish history.

During their trial the brothers claim to have been working for the British Government against the IRA. They say they had been told to stage the robbery to discredit the republican organisation and force the Irish Government to introduce tougher measures against its members. The British Government, however, denies all knowledge of the brothers.

Kenneth is sentenced to twenty years while his brother receives a fifteen-year term. During their time in prison the brothers exhaust all the appeals processes, with their final appeal being turned down in January 1974.

The brothers escape from Mountjoy during an exercise period. They scale the 25-foot-high main prison wall with homemade ropes while other prisoners distract the guards. However, the pair is spotted as they climb an outer wall.

Keith, 29, who has injured his ankle, is recaptured near the prison. Kenneth, 32, however, disappears without trace and is believed to be heading for the border with Northern Ireland. He is recaptured in December 1974. The brothers are released early in 1981 on condition they leave the Republic of Ireland.

Keith’s successful bid for freedom comes as a surprise. He has been weakened by a hunger strike he has been conducting since February in support of a demand for political prisoner status.

From the time the brothers are jailed the British Government steadfastly continues to deny all knowledge of them.

But the brothers’ tale does receive partial validation the prior year. Ireland’s former Taoiseach, Jack Lynch, admits he had been given diplomatic reports from the British authorities in January 1973 about the UK’s contact with the Littlejohn brothers.

In 1982, Nottingham Crown Court jails Kenneth Littlejohn for six years for his part in a £1,300 armed robbery at the Old Manor House, North Wingfield, Chesterfield, England. Keith Littlejohn, however, is cleared of a similar offence.
