Four people are fighting for their lives after a crush at a London music venue.

It happened at the Brixton O2 Academy, where singer Asake was due to perform.

Police were called to reports of a number of people trying to get in without a ticket at around 9.30pm.

The show was stopped halfway through and fans were reportedly told that ‘3,000 people had breached the door’.

Videos posted on social media show people flooding into the venue after getting past security.

Other footage shows police struggling to force a large crowd back away from the main entrance of the Stockwell Road venue.

The concert was the final performance in a three-night run by the popular Nigerian Afrobeats singer.

Eight people were taken to hospital and four remain in a critical condition.

While no arrests have taken place, detectives from Specialist Crime have launched an urgent investigation and cordons remain in place.

Met Police gold commander Ade Adelekan described the incident as ‘extremely distressing’. 

Mr Adelekan continued: ‘I am aware of video being shared on social media. 

‘I would ask people to be sensible about what they share, and not to post material that will be upsetting to those affected by this incident.

‘Where force has been used by police officers, those officers know they have to be accountable for their actions. 

‘The Met’s Directorate of Professional Standards will view all material, including Body Worn Video footage from the officers at the scene.

‘In relation to a clip being widely shared, I can confirm that no police dogs were deployed to the location.’
