Murdered loyalist Alan McCullough was a military intelligence spy who double-crossed both factions of a feuding terror organisation, his killers claimed.
As detectives continued to question a man about the murder, the Ulster Defence Association also accused McCullough of being heavily involved in four assassinations.
The paramilitary grouping provoked a wave of revulsion for killing McCullough, a former ally of ousted loyalist Johnny Adair, after apparently agreeing to lift a death sentence against him.
The 21-year-old fled to England after the UDA drove supporters of Adair’s ruthless C Company unit out of Northern Ireland at the height of the internecine war.
But in a statement issued the UDA claimed it wanted to set the record straight “once and for all”.
It said: “Alan McCullough was an MI5 agent who “Judased” both the UDA and his murdering mates in C Company who were exiled from Northern Ireland.
“McCullough was military commander of the notorious, now defunct, C Company who gave the orders for four murders, numerous gun and bomb attacks and death threats throughout Northern Ireland.”
A brutal power-struggle between Adair and his rival UDA commanders saw four men shot dead either side of the New Year.
Among those killed were the organisation’s hardline South-East Antrim brigadier John “Grug” Gregg and his associate Robert Carson near Belfast docks.
