Four people were hospitalized in critical condition on Friday after hundreds of people forced their way into a London concert venue during a performance by Nigerian Afrobeats star Asake.
Police said eight people were taken to hospitals after being caught in a crowd of people trying to get into the O2 Brixton Academy. Two other injured people were treated at the scene.
Police said emergency services were called Thursday night after �a large crowd attempted to gain entry without tickets.� Video footage shot by bystanders shows a crowd of hundreds outside the concert hall, and scores of people pushing through the doors and rushing upstairs.
The concert was halted, with a promoter going onstage to tell the audience that people had �breached the doors.�
The Metropolitan Police force said officers, ambulance crews and firefighters arrived and found �a number of people with injuries believed to have been caused by crushing.�
London Mayor Sadiq Khan said he was �heartbroken that this could happen to Londoners in our city.�
�I won�t rest until we have the answers their loved ones need and deserve,� he said on social media.
The police force said it would hold a thorough investigation into what happened and how officers responded. One piece of footage shows an officer appearing to shove a woman down a few stairs at the venue entrance.
Metropolitan Police Gold Commander Ade Adelekan said officers who use force �know they have to be accountable for their actions.� He said officers� body-worn video footage would be studied as part of a probe into the incident.
�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,� he said. �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 Brixton Academy in south London is one of the city�s most famous music venues. Built as a movie theater in the 1920s, it has a capacity of just under 5,000.
