Multiple rescue crews and a coastguard helicopter were called to the incident.

The pair were diving around the HMS Scylla which was sunk in 2004 to create an offshore reef. It has since attracted thousands of divers to the area.

Falmouth Coastguard was alerted to the incident at Sennen Cove on 6 August. 

Police say they were informed the diver did not resurface just after 9am on Wednesday 28 July.

The Maritime and Coastguard Agency are warning people to take extra care if they're heading out to sea.

This week marks the 20th anniversary of one of the most remarkable rescues in maritime history - after a mayday message to the coastguard.
