Thirty people have been confirmed dead as a result of the blaze that ripped through a London tower block, police said on Friday, as Queen Elizabeth II and Prince William visited survivors. He says it will take weeks or longer to recover and identify all the dead at the building.
Fifty-eight people are still missing after the Grenfell Tower fire and are presumed dead, police say.
He said: 'For me, this is a human tragedy'.
Residents said they had been complaining for years about lax standards while aspects of a recent $13 million refurbishment to the building have fallen under suspicion of allowing the fire to spread more rapidly than expected.
Cundy said there may have been other people in the tower that police are not aware of, which would add to the final death toll.
"The reason we had to pause the search and recovery yesterday was for the safety of our staff".
Cundy promised an "exhaustive investigation" into the tragedy and said "my heart goes out to those affected".More news: Furious Trump blasts Comey sacking probe 'witch hunt'

Firefighters raged against the inferno for more than 24 hours and the frantic fight has left its mark.
Moments after leaving St Clement's Church, Downing Street announced plans for a £5million relief fund for emergency supplies, food and clothing during a meeting with survivors of the Grenfell Tower disaster.
London has a chronic housing shortage even in the best of times, and those left homeless by the fire - already angry over what they see as government inequity and incompetence - fear being forced out of the British capital.
Following the meeting, May released a strongly-worded statement in which she said on-the-ground support for families in the immediate aftermath of the blaze "was not good enough".
The identification of the victims is proving very hard - which experts attribute to the extreme heat of the fire.
Angry residents stormed local authority headquarters on Friday demanding justice as the death toll from the London tower block fire reached 30, with dozens more unaccounted for.
Police have warned some of the victims may never be identified due to the state of the remains. This relies on dental records, fingerprints and DNA when possible and also features like tattoos or scars.
Demonstrators from the Grenfell Tower area had gathered to protest the council's failure to act on warnings over fire safety in the building.
She said it was "difficult to escape a very sombre mood".
