A post-mortem examination is expected to be held tomorrow after a sea-diver drowned off the coast of Donegal.
Gardai are treating the death of John Allwright (57) who got into difficulties with a group of divers near Portnablagh on Friday afternoon as a tragic accident.
Sources said Mr Allwright was swept by an under-water current into a cave and his oxygen mask became dislodged.
Efforts were made by fellow-divers to replace the mask as Malin Head Coast Guard was alerted and Mulroy Bay Coast Guard and Sligo’s Rescue 118 helicopter went to the scene.
A spokesperson from Malin Head Coast Guard said the 57-year-old diver was not responding when he came to the surface.
"We were initially alerted by the gentleman's fellow divers. He was unconscious when he came to the surface and subsequently airlifted to hospital.
"There was an ambulance at the scene and also a garda presence who are investigating the matter," the spokesperson said.
Defibrillator assistance was applied but Mr Allwright was pronounced dead on arrival at Letterkenny University Hospital after the Friday afternoon tragedy.
Mr Alwright, from Langford, Bedfordshire, was with a group of English divers on a visit to Donegal.
A garda spokesperson told the Irish Independent that it is currently investigating the "tragic death".
"We confirm that we were at the scene where the man's body was recovered.
"We are treating this incident as a sudden death under tragic circumstances.
"We expect the post mortem will take place tomorrow," said the Garda spokesperson.
