These heart-stopping pictures show a group of thrillseekers scaling a 300ft high crane – and then hanging off by ONE HAND.
The daredevil students spend their time freerunning around Brighton, climbing high buildings and leaping off urban obstacles.
They reached their high point on the crane earlier this summer when they got into a building site near the train station.
Jack Bennett, 19, filmed as he and three teens scaled the huge red rig at sunrise and feareless Jake Deacon, 19, hung off the metal arm by one hand with no safety gear.
Jack, a graphic design student, said: “We just did it for the view and the adventure.
“We went there early in the morning because we didn’t want to disturb anyone. We didn’t want anyone to see us and get worried.
“We all do a lot of extreme sports and wanted to just overcome the challenge of climbing the crane.
“The view was amazing. We decided to walk along the arm of the crane all the way to the end.
“This was the most exciting part, however we didn’t want to stay up there too long in case of getting spotted and worrying someone.
“We could see the whole of Brighton – the sea, the wheel and the pier in the mid dawn light.
“Jake, one of my friends, said he wanted to hang off. I would never do that, but he was confident and went for it.
“I wouldn’t say I was freaking out, but as soon as he did it I was like ‘come back up now’.
“We were up there for five or ten minutes and then came down.
“We headed home on a huge high after a crazy awesome adventure.
“We all had work the next day, so had a great story all to share.
“We don’t plan on stopping urban climbing, parkour or free running any time soon.
“It was a great adventure, but we don’t want to inspire anyone else to do this.”
