Twenty fans brawled at a Robbie Williams concert.

Around 60,000 people paid up to £300 to see the 'Candy' singer at Wembley Stadium in London on Sunday (30.07.13), but a fight erupted, with assailants throwing kicks and punches in front of the rest of the terrified crowd.

In video footage of the brawl, a man in a red T-shirt can be seen battered to the ground as beer was thrown at him. A bald man then delivered blows to the floored victim after having the shirt ripped off his back.

Shocked concert-goers backed away from the huge brawl in attempts to stay safe, as Robbie, 39, sang 'Sin Sin Sin' near the end of the show gig.

The violence escalated as women seemingly joined in to defend others before security attempted to diffuse the altercation.

Disappointed fans took to Twitter to express their anger at the way security handled the fight, with one fan known only as Charlie tweeting: ''Wembley security is so s**t would think twice about going again.''

Although the brawl was violent, no criminal charges have been brought against anyone, with Wembley officials confirming: ''There was an altercation. No one wished to press charges.''

Robbie has yet to comment on the fight.
