A 19-year-old British sailing instructor has died while swimming in Greece.
Harry Byatt, who worked in Zakynthos, an island in the south-west of Greece, failed to resurface after diving into the sea, his employer said.
The former Eastbourne College pupil's body was found on the seabed at a depth of around 98ft (30m) on 6 August.
A memorial page has been set up paying tribute to a "beloved son, brother, and friend".
The Peligoni Club, where Mr Byatt worked as an instructor, raised the alarm five minutes after he began swimming underwater using a monofin and a mask, a spokesman for the resort said.
Mr Byatt was found unconscious and brought to the surface where CPR was administered, but doctors and medical professionals could not revive him.
Son, brother, friend
A statement from the East Sussex college where he studied before becoming an instructor said its community was "deeply saddened" by his death.
"Our thoughts are with his family at this incredibly sad time. The college and CCF (Combined Cadet Force) flags will fly at half-mast at the beginning of next term."
It went on: "His parents and sister have asked us to let the college community know and to advise that further details about arrangements will follow in due course."
The Peligoni Club said it was working with local authorities to investigate the incident.
A spokesman said: "Three doctors, two guests from the UK and one local doctor, and an army medic from the UK did everything they could to revive him on site whilst awaiting the ambulance."
A Foreign Office spokesman said: "We are supporting the family of a British man who died in Zakynthos, Greece and are in contact with the local authorities."
