A video of a burning cardboard model of Grenfell Tower, the West London apartment building where 72 people died previous year, has drawn criticism, including from UK Prime Minister Theresa May, who called the act "utterly unacceptable".
Seventy-two people died in June 2017, after a fire engulfed the 24-storey west London apartment block.
The cardboard cutout is marked "Grenfell Tower" and includes figures of people in the windows. To mock that disaster in such a crude way is vile.
"I am very pleased to hear that the authorities are taking the matter very seriously and that an investigation is underway".
It's a disgusting video.
"I know that the police have been made aware of this video and will work to establish whether any offences have been committed".
London Mayor Sadiq Khan attacked the video on Twitter, saying: "I utterly condemn this sickening video".
Prime Minister Theresa May tweeted that the video was "utterly unacceptable", while Home Secretary Sajid Javid dubbed it "disgusting, shameful, behaviour".
Khadijah Mamudu, whose mother and younger brother escaped the fire, told the Press Association: "Their actions upset so many people around the world and they need to think long and hard". "We're coming to get you!" yells another participant, referring to the promises of emergency workers who instructed residents to stay in place and wait for help - help that didn't reach them in time. "This is an appalling and disturbing video", she said.
"It can not be justified on any level".
It is not known when or where the video was recorded, or by who.
In the clip posted online, raucous laughter can be heard off camera as the effigy is set alight. "Help me, help me!" shrieks another, seemingly mocking the last words of some of the victims.
Another says: "Here we go", as the fire takes hold.
Another one makes ambulance noises before saying: "That's what happens when they don't pay their rent".
A similar flag was visible behind the Grenfell model in the video. The video showed one person saying: "That little ninja's getting it at the minute" - an apparent racist comment about a Muslim woman in a burqa depicted on the side of the model.
Speaking to Tom Swarbrick, Alex described the video as "hilarious".
