Brian Stack says family subjected to 'deception' as he continues to clash with Gerry Adams

The son of a man killed by the IRA says his family has been subjected to a "pattern of untruthful deception".

Portlaoise Prison officer Brian Stack was shot and killed in 1983. Gerry Adams claims he handed over the names of four suspects to the Garda Commissioner in February, after he was given them by Mr Stack's son Austin.
