SECURITY staff at Wireless Festival were overwhelmed by crowds fleeing the likes of David Guetta and Nicki Minaj.
Shortly after Clean Bandit took to the stage at Finsbury Park, crowds rushed the fences in a frenzied bid to break free and return to the outside world.
Security guards tried to in vain to prevent the horde of legitimate ticket holders from escaping, with the exit stampede intensifying as Ciara prepared to take the stage.
Guard Wayne Hayes said: “It was like they were possessed, they were actually gnawing the fences. The nature of the event coupled with the fear of an afternoon appearance by Jaden and Willow Smith had turned them into savage brutes.”
He added: “As festival staff we get to wear earplugs.”
Festival goer Stephen Malley said: “I bought my ticket on the strength of the poster, which looked colourful and fun. If only I had stopped to read the words.
“At one point I ran from Avicii only to find Arrested Development playing on another stage. Out of the frying pan, into the fire.”
