Gardaí in Donegal are questioning a 42-year-old man over the deaths of a couple in their 70s.
The bodies of the pensioners were found at their home in Carndonagh shortly after 9am this morning.
Shortly after, a man in his 40s was arrested, and is being questioned at Buncrana Garda Station.
The scene remains sealed off and the State Pathologist has been notified.
A hatchet found at the house is also to be examined as part of the investigation.
It is understood the couple died from multiple wounds.
A garda cordon has been put up to seal off the large, neat bungalow which is surrounded by gardens and is on the edge of the town on the Carn side of Mountain Road.
There were emotional scenes as relatives of the pensioners arrived at the scene earlier this morning.
Fianna Fáil councillor Martin McDermott, who knows the family, said people had been left numb by the deaths.
“The community is just numb,” he said. “You do not think things like this will happen on your doorstep but, sadly they do.
“It is a very sad day.
“The couple would be very well-known and were well-liked in the area. They have a big family connection in the town.
“I would have known them personally and would have worked with them as part of my own work.
“It really is a tragedy.”
