Rescuers were called to Mewslade Bay near Worms Head

Two other people are in "stable" conditions in hospital in Swansea.

Mr Bellew, 24, who lived in Cardiff but was originally from Somerset, was pulled out of the water at Mewslade Bay near Worms Head at 1200 GMT, Tuesday.

Coastguards said he was in a party who were coasteering which involves swimming, jumping and climbing cliffs.

It is understood Mr Bellew became separated from the three others in the group and could have been thrown against rocks by the rough sea.

Stable condition

He was winched from rocks and airlifted by the RAF crew from Chivenor in Devon to Swansea's Singleton Hospital where he later died.

A Morriston Hospital spokeswoman said two people were being treated and both were in a stable condition.

It was the wrong weather conditions for what's a fun thing to do on a nice day RAF spokesperson

Bernie Kemble, watch manager with Swansea Coastguard, said when rescuers reached the coasteerers "one of the guys on the rocks was in a bad way".

"The helicopter arrived and winched him up pretty quickly and took him to Singleton Hospital when later he was pronounced dead."

He described the weather at the time as "atrocious, with a south westerly wind, gale force eight, poor visibility and rough seas".

The RAF spokesperson said the group who were coasteering - an extreme sport which first began on the Pembrokeshire coast - were appropriately dressed for the activity.

The group were wearing wetsuits, buoyancy aids and hard hats.
