The brother of Glenn Quinn murdered by members of the South East Antrim UDA has been warned by police within the last 24 hours that his life is under imminent threat.
It is the second time Martin Quinn has been told he is in danger and believes it is all because his family have gone public in their fight for justice.
Glenn Quinn, 47 and from Carrickfergus, was found dead in his ground floor flat at Ashleigh Park in the Woodburn area of the Co Antrim town in January of this year.
Following a post-mortem examination, officers launched a murder enquiry, saying Mr Quinn had suffered a blunt force trauma that they believed resulted in his death.
Martin Quinn told UTV that after police called to his home in the early hours of Thursday, he knew that this sort of threat was serious.
"I was told that elements within South East Antrim UDA intend to carry out a violent attack and firearms can't be ruled out. I felt sick to my stomach and angry," he said.
The DUP's Sammy Wilson has condemned the 'despicable threat' against Martin Quinn.
He said: "The Quinn family have suffered enough and those who have issued those threat have no place in Northern Ireland.
"The community stand with the Quinn family and all those seeking justice. "
