One of the UK's only remaining manufacturers of diving suits, based in Bradford, has helped a daredevil fundraiser on his way into the record books.

Divers Warehouse, based in Dudley Hill, designed and made a dry suit for Graham Bounas last year as he walked across the River Humber to raise money for charity.

Mr Bounas walked across the river's mud flats at low tide to raise £40,000 for DEBRA UK, a charity which raises money for children suffering from rare skin blistering conditions.

So successful was the mission, that the fearless fundraiser has taken on further challenges.

Just last week he became the first person to walk across the River Mersey without the aid of a bridge, using the suit he had made in Bradford.

And now the father-of-two is returning to his home town of Hull to tackle a gruelling underwater challenge.

Tomorrow he is to return to the River Humber, only this time to walk along the bottom.

For the 43-year-old, who is a towering six-feet nine-inches tall, this will be the first time he has faced the murky depths of the river.

He became involved in raising money for sufferers of the skin-blistering condition epidermolysis bullosa (EB) after meeting youngster James Dunn, 12, who lives with EB.

Mr Bounas said: "These challenges are risky and they take a lot of training and dedication. But I am not being brave - bravery is living with a condition like EB.

"James and everyone else who goes through the pain and suffering of EB are heroes to me and I am determined to raise £100,000 for DEBRA so that one day they no longer have to suffer."

Mr Boanas runs an electrical company and on all previous fundraising attempts has kept his head above water by wading across the rivers at low tide.

However, on this occasion he will attempt to cross the River Humber by the footings of the Humber Bridge where the river can plummet to depths of six metres at low tide.

For the challenge Mr Boanas will once again be donning his specially-adapted dry suit, which features stainless steel rings to drag him out of the water in the event of an emergency, but will this time add a series of weights to keep him on the bottom of the waterway.

John Womack, of Divers Warehouse, who made the suit, said: "The suit he has got will be able to last him for life. It is light but will keep him protected."

During his latest challenge Mr Boanas will be supported by Northern Divers as he walks more than a mile underwater from the south bank to the north bank from around 11am on Sunday.
