A woman has died after being injured in a crush at a concert in Brixton, south London, on Thursday.
Rebecca Ikumelo, 33, of Newham, died this morning in hospital.
A post-mortem will be held on Sunday at the Greenwich Public Mortuary.
Two other women, aged 21 and 23, remain in a critical condition.
Eight people were taken to hospital with injuries following the incident on Thursday night.
Speaking at the scene on Friday, Chief Superintendent Colin Wingrove, commander for Lambeth and Southwark, said: “I’d like to extend my sympathies to all those who have been affected. Having seen some of the really upsetting images on our thoughts are with them.”
He said detectives are carrying out an urgent investigation, including trawling through a ‘vast’ amount footage on social media, as well as police body worn cameras.

Police said they were called to reports of a “large number of people attempting to force entry to the venue”, where Afrobeat artist Asake was performing.
The singer was forced to abandon the gig after performing three songs and later released a statement saying his “heart is with those who were injured”.
An MP has called for answers over what led to the crowd crush.
Florence Eshalomi, Labour MP for Vauxhall, said: “It is very clear ticketing and security procedures have not performed as they should have for this incident to have occurred.
“We need answers about exactly how this happened and safeguards against it in future.”
She added: “This is a deeply concerning incident and has turned an experience which should have been a celebration into a very sad day.”
The incident has been referred to the police watchdog, the Independent Office for Police Conduct, which said it was assessing footage of what happened.
