A 50-year-old man has died after suffering a cardiac arrest while diving at a quarry in Snowdonia.
Emergency services were called to Dorothea Quarry just before 1pm on Saturday.
An air ambulance and an RAF rescue helicopter were flown to the scene, but the man died despite efforts to save him.
North Wales Police says the man's family has been told, and the Gwynedd coroner also informed.
The quarry, in the Nantlle Valley, is a popular site for divers.
