Footage, filmed on Saturday, appears to show a fight breaking out in the crowd shortly before Anthony Joshua was due to fight Eric Molina in the ring.

The filmer wrote online: "This was shortly before the main event of the night. Anthony Joshua Vs Eric Molina.

"Both men were competing for IBF world heavyweight title of the world with Joshua defending it."

"The fighting broke out shortly before the last fight of the night and just after the last undercard bout, Derik Chisora Vs Dillian White," he continued.

"Someone was stood up after the split decision in White's favour and someone was unhappy about this so he threw his alcohol beverage over him and people began to argue.

"Sensing there was tension I decided to go the toilet but half way there the song sweet Caroline came on so I decided to start recording and head back to my seat this is when all the fighting I recorded took place."
