Health Minister Simon Harris has urged Gerry Adams, and all of his associates, to make available any information regarding the killing of prison officer Brian Stack in 1983.

Minister Harris says no one should forget that at the core of the matter is a grieving family who has lost a loved one and is still looking for answers.

He says he is not satisfied by Mr Adams explanation in relation to people involved in the killing of prison officer.

"No, not at all, and I don't think anybody really could.

"It seems to be very perverse and peculiar that an organisation seems to say 'Well we dealt with this matter through disciplining a member' - as though disciplining a member, whatever that even means, is an adequate alternative for the laws of the land and the structures of An Garda Síochána and our courts system."

Mr Harris says no one should forget that the grieving Stack family is at the core of the matter, and is still looking for answers.

"That has to be what we all want to establish here - not political point scoring, but rather making sure that the Stack family can have answers to questions that still remain unanswered.

"One can't even imagine the grief and the pain that that family went through, and that can only have been compounded further by the lack of answers.

"So I really - and I mean this sincerely, and I mean it in a non-political, non-partisan sense - I really do urge Gerry Adams and any of his associates to make all the information available" he added.
