A man has died following an organised dive at a sunken Royal Navy warship off the Cornish coast.
The man, aged in his 30s, from Romford, Essex, was at HMS Scylla in Whitsand Bay with 10 other divers.
He was rescued on Sunday and taken to Derriford Hospital where he was later pronounced dead.
A post-mortem examination is due to be held on Monday. Devon and Cornwall Police are making initial inquiries for the Health and Safety Executive.
The man had been diving at the wreck with a partner.
He was rescued and carried to the shore by the dive boat and air-lifted to hospital. His next-of-kin have been informed.
Thousands of divers have visited the Scylla, which was sunk in 2004 to create Britain's first artificial reef.
It is run by the National Marine Aquarium in Plymouth.
