Sinn Fein MP Conor Murphy has said he will not be intimidated after receiving a death threat.
Mr Murphy, who represents Newry and Armagh, received the telephone threat at his Newry constituency office on Tuesday.
The caller claimed to represent the UVF. He told Mr Murphy he would be shot in his home.
The senior Sinn Fein politician said he reported the incident to police.
"Considering the antics of the UVF in Belfast of several months now we took the threat seriously," he said.
