Sinn Féin TD Martin Ferris has revealed why IRA murdered Stack
Murdered prison officer Brian Stack stood up to the IRA's attempts to take control of Portlaoise Prison in the 1970s and early 1980s, Sinn Féin TD Martin Ferris has revealed.
Mr Ferris is one of four senior Republican figures linked by Gerry Adams to the cowardly murder of Mr Stack in 1983.
The Kerry TD was the Provos commanding officer in Portlaoise during his time in prison for gun-running. Mr Ferris denies any knowledge or involvement in the murder of the Chief Prison Officer at Portlaoise.
However, in his authorised biography, Mr Ferris is scathing of Mr Stack and outlines the continual clashes between the authorities and IRA prisoners.
The Provos wanted their own command structure to contol the prison. But the prison governor and his senior officers, led by Mr Stack, battled to maintain control for the State.
"Stack was a particularly vindictive individual. He would never forget a previous incident, and if he took a dislike to a certain prisoner, he would wait until a suitable opportunity arose to punish the man in some way or other," he says in the book, published in 2005.
