A body has been recovered from the water at Slieve League in County Donegal.
A major search operation has been ongoing in the area since last weekend – with investigators concerned a missing person may have been seriously assaulted.
Gardaí had been treating the investigation as a potential murder case.
This morning, Gardaí recovered a body from the water with the help of the Coast Guard.
The body has since been removed to Letterkenny University Hospital and a post-mortem will take place in due course.
Missing
Last week, sources said Gardaí believed the missing man was in his mid-60s and originally from Northern Ireland.
Investigators were liaising with police in Northern Ireland in a bid to determine his whereabouts and were working to make contact with his family.
At the time, nobody had come forward to report the man as missing.
On Thursday, Gardaí began a new search around a pier in the area.
The road to Teelin Pier, which is about a kilometre away from Slieve League was closed while the Garda Water Unit carried out the searches.
Witnesses
Gardaí say they are continuing to investigate an alleged assault that is reported to have happened in the Slieve League/Killybegs area.
They are appealing to anyone who was travelling in the area between the afternoon of Saturday 24th June 2023 and the evening of Sunday 25th June 2023 and saw anything that drew their attention to come forward.
They are particularly interested in talking to drivers who were in the area and may have camera footage.
Slieve League or Sliabh Liag is a mountain on the Donegal coast that boasts some of the highest sea cliffs in Europe.
