The gruesome scene unfolded on the striking glass dome of the mall this morning after a security guard was carrying out his morning rounds.
Strangely enough, the mystery intruder was spotted after recent reports suggested you are most likely to spot a werewolf in the North.
The shocked store security guard spotted the beast on the roof as it capered in the shadow of the imposing Holy Trinity Church.
Security guard Stuart Hoyland said: “I heard the patter of paws whilst doing my rounds this morning and looked up to see a shadow of red dripping down our main glass dome roof, with a large shadow I didn’t recognise.
“It was especially odd as only the cleaners are allowed up there and they came yesterday.
“I went up to the roof of the Everyman Cinema to take a closer look and saw this giant Werewolf howling across the city – I’ve heard rumours of supernatural creatures like this but never seen one before, it was terrifying!”
An onlooker said: “As Halloween stunts go, this was a good one!”
