Four revelers fight for their lives after collapsing at the O2 Academy in Brixton

Four people were left fighting for their lives after a concert was thrown into chaos last night when fans were accused of trying to enter the venue without tickets, prompting an alleged crush.

Police were called to the Brixton O2 Academy on Stockwell Road, south London, on Thursday at 9.35pm after a large number of people reportedly attempted to force entry into a concert without tickets.

When officers arrived outside the scene where Afrobeats singer Asake was scheduled to perform, they found a number of people with “injuries believed to have been caused by crushing”.

Eight people were taken to hospital, four of whom are in critical condition.

No arrests have been made and detectives have launched an urgent investigation with cordons remaining in place at the O2 Academy this morning.

Fans were filmed clashing with police outside the O2 Academy in Brixton – one was pushed down the stairs and another put in a headlock after punching an officer in the face.

At least four were left in critical condition after suffering “contusion injuries” after what appeared to be a rush at the sold-out show, which was cancelled.

Footage shared online showed dozens of people making their way through the narrow front doors as a reveler said: “It’s so dangerous.”

Another clip shows hundreds of people packed like sardines in an alleyway next to the venue.

Meanwhile, a video shared on TikTok captured the moment Asake told his fans that “3,000 people broke down the door outside.”

In the video he said: “Because of the security police asked us to close the show. We apologize to you, this has nothing to do with us or the organizer. That’s basically… listen to what I’m saying.’

He then hands over the microphone and fans are told to “leave the way you came” and promised that they will get a refund for their purchased ticket.

In other video content, the venue crowd can be heard booing as it was announced from the stage that the show was closing.

The gig, which saw Asake touring his debut album Mr. Money With The Vibe, was canceled midway.

It was the finale of three sold-out shows performed by the Nigerian singer – who had 2020 breakout hit Lady – at the Brixton Music Venue, which had a standing capacity of 5,000 people.

On Sunday, the musician tweeted fans to ask them not to come to the O2 Academy if they didn’t have a ticket, adding that it was sold out and no tickets were sold at the door.

Met Police Gold Commander Ade Adelekan described the incident as “extremely disturbing” and urged any witnesses who have not yet spoken to police to get in touch.

Mr Adelekan added: “I am aware of videos being shared on social media. I would like to ask people to be sensible about what they share and not to post any material that may upset those affected by this incident.

“When cops have used violence, those cops know they must be held accountable for their actions. The Met’s Directorate of Professional Standards will review all footage, including body-worn video footage of the officers at the scene.

“Regarding a widely circulated clip, I can confirm that no police dogs were used at the location.”

The person who tweeted the video claimed, “So the police cordoned off Asake and left a bunch of people in an alleyway in the freezing cold.”

Elsewhere, a woman is seen confronting a Metropolitan Police officer.

She is quickly swarmed by four other officers as she is brought to the ground. It is still unclear whether she was arrested.

Another shocking video shows a woman arguing with an officer at the top of concrete steps outside the venue before being thrown off by the officer.

MailOnline has reached out to representatives from Asake and O2 Academy for further comment.

The London Ambulance Service said they were called to Brixton 02 Academy at 10.06pm.

10 people were treated at the scene, eight hospitalized and two discharged.
