A man who died in a diving incident off the coast of Lowestoft in Suffolk is thought to be a 49-year-old man from Brixton in London.
Police were contacted at around 3.30pm yesterday to reports that a diver had died and was being airlifted to the James Paget Hospital at Gorleston.
The incident happened about 17 miles offshore.
A second diver brought ashore by the Gorleston lifeboat was taken to the James Paget Hospital for assessment but was later discharged.
An investigation into the incident is ongoing. Officers have already spoken to the other six people onboard the boat at the time.
The death is not being treated as suspicious.
