A MYSTERIOUS 'crop circle' has appeared next to the site of a festival near Winchester.

It was first spotted last Sunday (August 3) and can be found in fields next to BoomTown Fair which continues this weekend at Matterly Estate.

Sgt Mark Lamper, BoomTown acting inspector, said: “I don’t know who has done it. I flew in from Spain on Monday and you can see it from the air. As you drive along the A31 from Winchester, with BoomTown on your right, you can see it.”

A BoomTown spokesperson said they 'know nothing about it'.

The festival started on Thursday (August 7), attracting 38,000 revellers to see performances from the likes of Shaggy, Bellowhead and Ms Dynamite.
