As a regular concert goer, Mr Hargreaves estimates he has been to Wembley about 65 times. “The floor was slippier than I’ve ever known it at Wembley, or at any other concert I’ve been to.

“I was walking down some stairs with a drink in each hand for me and my wife and the next thing I knew I was up in the air. It all happened so quickly.”

His legal representative Matthew Tomlinson at Slater and Gordon said the firm was investigating the cause of the incident.

But the firm cited reports of other Oasis fans who had attended the Wembley shows saying the floor was “like an ice rink”.

Another fan, Lee Claydon, died after falling from a height at the Oasis show the night before. An inquest into the cause of his death has been opened and adjourned for a further pre-inquest hearing, set for 19 November.

The Wembley Stadium spokesperson said: “All accidents and incidents that take place at Wembley Stadium are reported and investigated thoroughly.

“On this occasion the guest was taken to the medical centre and assessed by a doctor who treated a wound and advised he be transferred to hospital immediately for an x-ray and further examination.

“The guest refused the medical advice provided and discharged himself so he could return to the concert.”
