A man who disappeared at sea was reportedly stung by a jellyfish while swimming in the River Mersey.
Haydn Griffiths, from Wigan, was last seen at Derby Pool in New Brighton when he went swimming with a friend at around 10.30pm on Tuesday night.
Haydn, who should have been celebrating his 24th birthday on Friday, was trying to swim out to the wind turbines which line the coast when he disappeared beneath the water and failed to resurface.
