The father of a man whose murder is being investigated by the North's Police Ombudsman's office has been warned that he is under threat of an 'imminent' attack by the UVF.
Security is being intensified at the home Raymond McCord - whose son was killed in 1997 by loyalist paramilitaries - after he received two new death threats inside 24 hours.
Nuala O'Loan's office has been examining the RUC investigation into the killing of Raymond McCord jnr in 1997 following claims that at least one of those involved was also an RUC Special Branch agent.
It is thought Mr McCord has been targeted due to his involvement with Police Ombudsman Nuala O'Loan's major investigation into the killing of his son.
Her inquiry, centred around claims that a Special Branch informer who ordered the former RAF man's murder in 1997 was shielded from prosecution, is believed to have uncovered damning evidence.
With the Ombudsman's report due to be published next month, police went to Mr McCord's home in Belfast on Wednesday and again yesterday.
On both occasions they alerted him to threats from the UVF's Mount Vernon gang in the north of the city who beat his son to death and dumped his body in a quarry.
Mr McCord, who has defied previous threats during his nine year justice campaign, insisted he would not be silenced. "I'm concerned but not frightened," he said. "The UVF leader in Mount Vernon hasn't the guts to come after me himself."
