A rescue operation was launched off Port St Mary this afternoon after a diver became ill.
Port St Mary lifeboat was launched and the Sea King rescue helicopter from RAF Valley scrambled.
A Coastguard spokesman said a group of divers had been in the water around the Sugarloaf by the Chasms and the dive vessel raised the alarm when one of the team was unwell when they surfaced. He was given oxygen but was unresponsive.
The unconscious diver was brought back into Port St Mary harbour on the dive vessel where he was given treatment by paramedics.
