A terrifying video has emerged of daredevils "lift surfing" in a UK's city's tallest building.
The worrying footage shows a young man recording himself while dangerously standing on top of the moving escalators.
The video, posted onto YouTube by an account with the username RYEGI, shows what appears to be two men standing on top of a lift in the dark as it ascends and descends the elevator shaft of what is said to be St. Paul’s Tower - a building that has held the title of Sheffield’s tallest building since its construction in August 2010.
