Ade Adelekan, the Met Police Gold Commander, said: “I am aware of video being shared on social media.
“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.”
The Telegraph understands that the incident will be referred to the police watchdog.
A spokesman for the Independent Office for Police Conduct said: “We are aware of the incident at the O2 Academy in Brixton, and the Metropolitan Police Service has advised it will be referring the matter to us.
“We will assess the available information, including footage of the incident, to determine what further action may be required.”
The crush is thought to have happened when people without tickets attempted to gain entry to the venue on the third and last night of a series of performances by Asake. The concert had started when there was a stampede outside, leading organisers to cancel the event.
