ASINIA BYFIELD’S incredible win over Sam McNess sparked a sickening mass brawl inside the London Copper Box with women and children caught up.

The Southern area super-welterweight title clash was won by the champion but it sparked terrifying scenes as bottles were thrown and chairs used as weapons.

The support for McNess was incredible as a whole side of the Copper Box suddenly stood and sung for their man in claret and blue.

It looked like the old Upton Park chicken run had also been transplanted to the old Olympic Village as diehard West Ham fans backed their man.

Songs about bubbles, Mother Brown and McNess being ‘one of our own’ echoed around the arena and the only surprise about McNess’ first round warning from the ref was that it was audible at ringside.

Byfield had ramped up the needle before the fight by claiming he could walk through West Ham’s East End home with his trousers down – if he wanted.

But the only flashes in Stratford were of brilliant fighting as Byfield dropped his hands and danced while the local hero grafted through the opening two rounds.

McNess was stung in the third round by half a dozen right hands and looked in desperate trouble before he rallied and wobbled the champion.

But Byfield – in a round of the year contender – spun the fight on its head again and seemed seconds from retaining his title, with a flurry, before the scintillating three minutes sadly ended to the biggest cheer of the night.

Byfield started the fourth round as a southoaw and taunted the 7-0 challenger with a squirt of right-hand jabs designed to do nothing more than demoralise McNess.

Byfield – aged 28 and with 13 pre fights behind him – insisted McNess, 25, was too inexperienced and out of his depth for this step and he proved his point in the fourth when he battered McNess.

The Hornchurch man summoned the strength of Julian Dicks to stay upright but he looked shot again in the fifth when Byfield seemed to be teeing off at will and damaging his opponent.

There were calls for the fight to be stopped – desperate pleas as McNess was out on his feet getting pummelled and finally the towel was throw in by McNess’ corner.

As Byfield celebrated a sickening fight broke out between the two sets of fans as the ring MC screamed for calm and bellowed “I can see children”.

It was claimed the rest of the show – including headline act Anthony Yarde – would be cancelled.

And even when the riot had been quashed, small pocket fights were breaking out.

The ring announcer yelled “Gentlemen, this is boxing not football” and warned the thugs that they were being filmed police and after around 20 minutes of mayhem it seemed calm was resumed.

A new fight between Ryan Garner and Tamas Laska started but another fight broke out outside the ring.

The time keeper had no microphone - due to the melee - so the officials wanted the fight to be stopped but it continued until Garner won well.
