The Kincora boys' home in East Belfast
A former Army Intelligence officer who worked in Northern Ireland during the 70s has told of how his investigation into allegations of abuse at the Kincora boys' home was blocked by MI5.
In an interview with the BBC, Brian Gemmel said that he was told to ditch the investigation into the boys' home by a senior MI5 officer.
Mr Gemmell's claim comes as calls for a full investigation into the allegations of abuse at the home intensify.
It was recently claimed that people of the "highest profile" were implicated in the scandal.
Three senior members of staff at the home were jailed back in 1981 for the abuse of 11 boys.
Mr Gemmell told the BBC that : "I was summoned to go and see him (the MI5 officer). I went up thinking he was going to be pleased with me."
"He bawled me out. He was rude and offensive and hostile."
Mr Gemmell said he was then ordered to "stop any investigation" into Kincora.
He added that the investigation into Kincora should be reopened, stating: "I think there's more hope than there has been in the past. Although there's not a lot, there is more than in the past."
