The search for a missing firefighter who was swimming the English Channel for charity has been called off.
Iain Hughes, crew manager at Wednesbury fire station in the West Midlands, set off from the Kent coast on Tuesday morning.
The 42-year-old married father-of-two was accompanied by a support boat but went missing later that day in French waters.
A search involving French and Belgian military helicopters, plus navy and police patrol boats, was launched but has now finished, French authorities said.
West Midlands Fire Service said Mr Hughes's whereabouts "remain unknown" and it is "heartbroken" by his disappearance.
"Iain's disappearance is unspeakably sad," said Chief Fire Officer Wayne Brown.
"He is a highly-respected and much-loved colleague and friend to many.
"We are giving Iain's family all the support we can at this distressing time."
According to Mr Hughes's JustGiving page, he had raised more than £5,000 of a £21,000 target for the British Heart Foundation, Firefighters Charity, and Midlands Air Ambulance.
He joined West Midlands Fire Service in 1999, at the age of 19.
