(Apparently the video doesn't have sound.)
Staff at Derby salon Sally Montague believe they have caught a ghost on a security camera.
Workers at the Iron Gate hairdresser were checking CCTV footage after a receptionist had her phone stolen, and were shocked to see a ladder moving on its own.
On closer inspection, they saw what appeared to be a hand materialise at the side of the ladder and pull it.
Directly beneath the corner where the ghostly goings-on happened is a secret underground tunnel leading to the cathedral, thought to have been used by nuns hundreds of years ago.
Salon owner Sally Montague said: "What we've caught on camera is very strange and I can't think of a logical explanation. None of us can work it out.
"It doesn't frighten me because strange things are always happening, like items going missing. But I definitely wouldn't want to spend a night there on my own."
