Six men arrested over a video showing a model of Grenfell Tower being burned while people laughed and joked have been released.
Scotland Yard has said the men, who were arrested on suspicion of a public order offence, have been freed from police custody but are still under investigation.
The suspects – aged between 19 and 55 – had all handed themselves in at a police station over the offensive video, which was met with public outcry after it was posted on social media.
The footage showed a large flammable model marked "Grenfell Tower", complete with paper figures of people at their windows, before it was set on fire.
As the flames climb up the model building, one of the people in the clip questions whether they should have put the tower on the bonfire upside down, because the Grenfell fire started on the 10th floor.
One person shouts "jump out the window" while another person says: "Stay in your flats" – a reference to the original fire brigade advice before the scale of the tragedy was understood.
Another voice can be heard saying "that's what happens when they don't pay their rent".
Police spent much of Tuesday searching the garden of a terraced property in London where the bonfire is believed to have taken place, with officers seen carrying evidence bags.
Earlier, Sir Martin Moore-Bick addressed the "offensive" video as he opened another day at the Grenfell inquiry.
"It must be shocking and distressing to all those involved, whatever form their involvement took, whether as bereaved, survivors or indeed members of the wider community," he said.
"I am very pleased to hear that the authorities are taking the matter very seriously and that an investigation is under way."
Theresa May was one of those who criticised the actions in the video, calling them "utterly unacceptable".

And Home Secretary Sajid Javid said the survivors of the tragedy – which killed 72 people – deserved to be treated with the "utmost respect".
