A HUGE brawl erupted on the streets of Glasgow last night after a major bare knuckle boxing event attended by Conor McGregor.

Cops rushed to the area outside the Hydro at around 11.10pm on Saturday when mass violence broke out.

The shocking scenes came after Bare Knuckle Fighting Championship hosted its first event in Scotland.

The headline fight in front of a packed arena saw ex-Rangers Riot Crew football hooligan Sean Weir brutally defeat Leigh Cohoon in the first round to claim the British light heavyweight title.

But within half an hour of the 34-year-old punching his way to victory police swarmed the surroundings after street battles broke out.

Footage captured by shocked residents showed dozens of men trading blows in the darkness while fans were spilling from the Hydro.

Cops were seen chasing after some of the yobs in a bid to break up the mayhem.

Officers then formed a barrier outside the Hilton Garden hotel to prevent people getting back into the zone.

The disorder – after what BKFC bosses had hailed as one of their best nights ever – sparked a massive police response with rows of cop vehicles lined up on the road at the approach to the entertainment hub next to the Clyde.

One onlooker said: “It was mayhem. There were groups of all going for each other.  It was pretty brutal to see the violence so close up. There were cops everywhere.

“The event itself was full of KOs and drama so it obviously got a bit too much for some in the crowd who wanted to try it outside the ring.”

Irishman Conor Cooke withdrew from the blockbuster clash at the eleventh hour with veteran Cohoon, 42, stepping up at the last minute.

But the Manchester man was finished off in the first round by unstoppable Weir in front of a raucous crowd including world record holder athlete Josh Kerr, ex-boxing world champ Josh Taylor and two-time World’s Strongest Man Tom Stoltman.

Irish UFC icon and BKFC co-owner McGregor also celebrated alongside Rangers-daft Weir as he lifted his belt.

The Notorious was left stunned by the 34-year-old’s performance and the electric Glasgow atmosphere — before hyping a massive stadium show and even pitching an Old Firm clash inside the ring.

McGregor said: “I wasn’t going to miss it for the world, Sean Weir, I’m blown away, I’m absolutely blown away.

“He’s a star, when you can command an audience like that and a victory like that, you are a seven figure bare knuckle fighter.

“Feldman, McGregor, the two of us together, we’ve got a million dollar fighter here on our hands, you know we’ve got Ibrox.

He added: “I’m in awe, I’m in awe. This crowd, in this region, loves their bare knuckle.

“Who can fight Sean Weir?

“Can we get a Celtic vs Rangers battle?”

Weir – nicknamed The Butcher after the Gangs of New York movie character – dedicated his win to young Rangers fan Robbie Frew, 10, who lost his brave battle against cancer last month.

Police Scotland said two men aged 32 and 27, were arrested and charged with offences including police assault, obstructing police and threatening and abusive behaviour.

They will be reported to the Procurator Fiscal.

Three men were arrested and issued with recorded police warnings for threatening and abusive behaviour and breach of the peace.

Three officers were assaulted during the disorder, with two of them requiring medical treatment.

Chief Inspector Paul Daley said: “Several officers were assaulted whilst carrying out their duties during disorder following an event at the Hydro in Glasgow on Saturday night.

“Violence against officers is disgraceful and will not be tolerated. Being assaulted is not part of the job and it’s extremely fortunate they were not seriously injured.

“Officers are carrying out extensive enquiries in relation to the disturbance which occurred and anyone found responsible will be brought to justice.”
