A woman has died after being injured in a crush at a gig at London’s Brixton O2 Academy that left several others hurt.
The concert, by Afro-pop singer Asake, had to be abandoned part-way through after a “large number of people” tried to force their way inside on Thursday, the Met Police said.
Mother-of-two Rebecca Ikumelo, 33, from Newham, east London, died in hospital on Saturday morning, the Met said.
Her family said she was a nursing graduate known for “care and kindness”.
Two other women aged 21 and 23 remain in a critical condition, police added.
Asake said he was “overwhelmed with grief” and “devastated” by her death.
The artist said he had spoken to Ms Ikumelo’s family and asked people to “keep them in our prayers”.
In a statement released through the Met, her family said Ms Ikumelo was an “adorable mother of two children who loved working with kids”.
Videos on social media showed the crowd stretching from the road outside to the venue’s doors.
Speaking at the scene on Friday, Ch Supt Colin Wingrove said: “I’d like to extend my sympathies to all those who have been affected.
“Having seen some of the really upsetting images on social media our thoughts are with them,” he added.
The force said more than 4,000 people were in attendance at the gig and it has set up a website for people to submit relevant photos and videos.
In a statement outside Brixton police station on Friday afternoon, Mr Wingrove said officers were called by staff at the venue “following reports that a large number of people were attempting to force entry”.
He added: “Some officers provided first aid and CPR to members of the public in order to save life.”
Florence Eshalomi, Labour MP for Vauxhall whose constituency includes Brixton, tweeted on Saturday: “I visited the site this morning and I’ve been dreading this news ever since the incident and hoping it would never never come.
“My thoughts and prayers to Rebecca Ikumelo’s family and friends. Such a tragic loss of a young 33yr with so much life ahead of her.”
The first officers were reported to be on the scene at 21:11 GMT, seven minutes after they were called.
The concert was the final performance of three sold-out shows at the venue by Nigerian singer Asake, sometimes known as Mr Money.
Before the gig, he had posted on Twitter asking fans not to try to gain entry unless they had tickets.
In a statement published on Twitter on Saturday, Asake said: “I am overwhelmed with grief and could never have imagined anything like this happening.
“My team and I are still awaiting the full debrief back from the venue management and the police to determine what exactly led to all the disruption caused and ultimately to Rebecca’s passing.”
He urged anyone with information to contact police.
