Gabriella Hutchinson, a 23-year-old female security guard, died as a result of injuries sustained during a stampede at a music concert hosted by singer Asake at the 02 Academy in Brixton, United Kingdom.
According to the Daily Mail, the victim died on Monday at a hospital four days after the incident on Thursday night, while working as a contracted security provider at the concert.
Hutchinson became the incident's second fatality, following the death of Rebecca Ikumelo, 33, on Saturday.
A third woman, 21, was still being treated and was in critical condition, according to the Metropolitan Police.
"It is devastating news that a second person has lost their life following the events on Thursday," said Chief Superintendent Colin Wingrove, policing commander for Lambeth and Southwark.
"I'd like to express my deepest sympathies to Gabrielle's family during this unbearably difficult time."
On Thursday, Asake's concert was called off in the middle after fans, many of whom did not have tickets, attempted to enter the venue by breaking down the doors.
At 9:35 p.m., police and other emergency services were called to the O2 Academy in Brixton after reports that "a large number of people were attempting to force entry to the venue."
Four people were critically injured, and another four were hospitalized.
Ikumelo, a mother of two, died on Saturday as a result of injuries sustained in the crush.
Asake tweeted the tragic news, expressing his condolences to the deceased's family and asking for prayers for them.
