Four people are in a critical condition following an incident at a concert venue in London.
Eight people were rushed to hospital from the O2 Academy Brixton and two who were less seriously injured were treated at the scene, the Metropolitan Police said. The incident happened during a performance by Nigerian Afrobeats singer-songwriter Asake on Thursday, December 15.
Lambeth Police said they are urgently investigating what happened in the "extremely upsetting incident". They said emergency services attended the venue in Stockwell Road following reports shortly after 9.30pm of injuries.
Metropolitan Police Gold Commander Ade Adelekan urged people to "be sensible about what they share" on social media and "not to post material that will be upsetting to those affected by this incident".
He also said that, where force has been used by officers, "those officers know they have to be accountable for their actions", adding that the Met's Directorate of Professional Standards will look at all material, including body-worn video footage from those at the scene. Police said no arrests have been made.
The Mirror reported that a cancellation announcement had been made on stage during the gig in which the crowd was told the show had to be stopped due to a breach of the doors. Mr Adelekan said: "This is an extremely upsetting incident which has left four people critically ill in hospital. My thoughts and prayers are with them and their families.
"A police investigation has been launched, and it will be as thorough and as forensic as necessary to establish exactly what happened last night. The scene will be examined by specialist officers, CCTV will be viewed, every witness that we can make contact with will be spoken to, and all other lines of inquiry will be followed.
"Officers are remaining in the area to provide reassurance to the local community in and around Brixton. If you have any information or concerns, please speak with them."
