A Brit has performed a “dangerous” Olympic-style dive from a bridge in full hi-vis gear.
Isaac Trueman-Marsden, from Sheffield, did a spontaneous jump from a makeshift board.
Footage shows the 22-year-old calmly strolling to the end before launching himself into the air.

He does an impressive twisting dive before plunging into the water below.
Isaac said that while the stunt was spontaneous, he and his friends checked the water’s depth beforehand.
But he has deliberately kept the location secret to discourage others from attempting to copy him, as he warned water levels at this spot can change.
“I would prefer if you didn’t say the location of the bridge just because I don’t want to influence people to do it because obviously it’s dangerous,” he told Whats The Jam.

“The depth also changes all the time at that location and I wouldn’t want anyone jumping when it’s not safe.”

Isaac and his pals constructed the makeshift diving board used for the spectacular leap themselves.
He said: “It was pretty spontaneous.
“We just checked the depth and jumped.

“We made the diving board as well.”
Despite the risky-looking stunt, Isaac is no stranger to throwing himself through the air and said he has been diving his “whole life”.
The incident took place on Sunday 6 September and has since gone viral.
His video has racked up more than 2.6million views and 82,000 likes.
Viewers were impressed by his technique – and amused by his unusual choice of safety gear.
One person said: “Absolutely beautiful technique.”

Another commenter wrote: “Old boy just checking the depth of the water on behalf of the council.”
One person added: “Highly irresponsible… Not wearing a hard hat.”

Someone else wrote: “Very dangerous to not have gloves on.”
