Footage has emerged of a woman being pushed down stairs by a police officer as chaos erupted outside a packed Asake concert last night.
Four people sustained critical injuries "believed to have been caused by crushing" at the Brixton O2 Academy around 9.35pm, following reports that a large number of people were attempting to force entry.
While no arrests have taken place, detectives from Specialist Crime have launched an urgent investigation and cordons remain in place at the O2 Academy.
