On 20 March 1975, Hugh Mooney, a member of the top secret Information Research Department run by the Foreign and Commonwealth Office, wrote a memo to his superiors claiming that the former Head of Army Intelligence in Northern Ireland told him that Colin Wallace "had been one of his best sources." MI5 accused Colin Wallace of leaking information to the press about William McGrath, the leader of the Loyalist paramilitary group Tara, who had been sexually abusing children at the Kincora Home. However, official records later showed that he had been instructed by his superiors to draw the attention of the press to McGrath's activities.
