A former senior police officer has said allegations that intelligence services were linked to abuse at Kincora Boys' Home may be credible.
Alan McQuillan said the claims needed to be investigated amid calls for the notorious home to be included in a UK-wide inquiry into child sex abuse.
Mr McQuillan, a former Assistant Chief Constable, said he had no proof of security service involvement. However, he added that the context around the time the abuse occurred meant it was "potentially credible".
"The allegation is there and it needs to be investigated," he told the Nolan Show.
Calls for Kincora to be included in the inquiry have received cross-party backing, and yesterday a victim came forward to add his voice to the pressure.
Clint Massey said: "I strongly believe there's a lot more to come out."
Mr McQuillan said including Kincora in the Westminster inquiry was vital, but "unless you get the active co-operation of the British Government and relevant agencies, then any investigation or public inquiry will get you nowhere."
