Five men have been arrested after a video was posted online - appearing to show a model of Grenfell Tower being burnt.
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.
In the video, members of the group can be heard laughing and shouting "help me, help me".
One voice can be heard saying "that's what happens when they don't pay their rent".
Police say the group - who are aged between 19 and 49 - are being held on suspicion of a public order offence.
Officers say they walked into a police station in south London last night.
It comes after British prime Minister Theresa May condemned the video, which emerged online, calling it "utterly unacceptable".
72 people died following last year's disaster.
