Revellers heading to the event this weekend have been warned that a wild feline is prowling the Worthy Farm site in Somerset.

Reg Baker, part of the build crew at the legendary music festival, claims that he saw a puma running across a field and claims that big cats living in the surrounding countryside is common knowledge.

Baker said: "I am part of the build crew at Glastonbury. I was walking around the site when I spotted a large black animal running free across the field.

"At first I thought it was a dog, but then I realised its running movement was different. From the shape, I'm pretty sure it was a puma."

He added: "They're common knowledge among the long-term workers and generally harmless - either hiding or leaving when the crowds arrive.

"Glasto is so big, it is possible a big cat could go undetected while trapped inside."
