Army bomb experts have defused a letter bomb left in a postbox in Co Down.
The viable device was discovered in the village of Clough. A spokesman for the Police Service of Northern Ireland said they had received reports of a man acting suspiciously at a postbox at Dundrum Road at about 9pm on Thursday.
He said: "Police investigating the report subsequently sealed off the area and tasked ATO to the scene. Examinations were carried out on a suspicious object found inside the postbox which was later described as being a viable device capable of causing death or serious injury. The device was made safe and taken away for forensic examination."
The largely Protestant village is just a few miles from an Army barracks at Ballykinler. Local elected representatives said there is not a public postbox on the Dundrum Road.
DUP MLA for the area Jim Wells said: "These things can kill. Maybe the intention was to intimidate or threaten but these types of devices are hugely dangerous. If they go off they can cause death or serious injury. I would appeal to anyone who knows anything to go to the police."
SDLP MP for South Down Margaret Ritchie said: "This sort of activity has to stop. All the activity of this week has to stop. We need paramilitaries to go away and get off the people's backs and leave them alone to concentrate on what is a really difficult economic situation."
