Jon Casterton scales some of Sheffield's tallest buildings, then abseils down, 'for a laugh'.
He was at it again yesterday, descending the Q Park building on Charles Street - otherwise known as the 'cheese grater -' in the city centre.
It took less than two minutes to come down, and Jon surprised a couple of passers-by when he landed next to them on the pavement on Arundel Gate.
Abseiling down tall buildings, he said, kept him out of trouble.
Park Hill Flats and the Cathedral Church of St Marie are among the buildings Jon has tackled.
"The higher the better," he said.
