Rev Dr Stewart Jones, 57, of Donemana Presbyterian Church near Strabane, Co Tyrone, died at Sligo General Hospital on Saturday night after he was airlifted. A 24-year-old man from Derry who got into difficulties with him was also taken to hospital, but he was later released.
Gardaí and emergency rescue services said the two men, who were friends, were diving near St John’s Point lighthouse when they got into difficulty.
They were on their second dive when they reached surface and they were suddenly hit by a freak wave.
