Theresa May has been meeting with victims, relatives and volunteers this afternoon
58 people are missing and presumed dead after the Grenfell Tower fire in London, police in London have said.
Metropolitan Police commander Stuart Cundy said: "That number 58 may change. I really hope it won't, but it may increase.
"Our focus has been on those we know were in there [...] However, there may be other people who were in there on the night that others were not aware were there."
He also added that he intends to release videos and images of the scene inside Grenfell Tower tomorrow, but stressed that he would not do that until all families affected had been contacted.
At least 30 people have been confirmed dead following the blaze.
Commander Cundy also formally identified the first victim of the fire as 23-year-old Mohammed Alhajali.
Meanwhile, victims, relatives and volunteers from the Grenfell Tower disaster have been meeting with Theresa May in Downing Street.
This is Mrs May's second meeting with those affected by Wednesday morning's fire, which was described as "unprecedented" by London's Fire Brigade Commissioner.
Mrs May has been criticised for not going to talk to victims until Friday, with furious locals shouting "coward" and "shame on you" following her visit with survivors at a west London church.
As the group of Grenfell residents and volunteers passed through the gates of Downing Street, protesters shouted angry chants about the Prime Minister and wore white ribbons as a sign of solidarity.
The No 10 meeting came after Mrs May chaired an emergency session of the Grenfell Recovery Task Force.
The cross-government group is coordinating the immediate and long-term response to the west London blaze.
Mrs May has announced a £5m (€5.7m) fund as part of a "comprehensive package" of support, with Downing Street.
