A relative of a men arrested in relation to the Grenfell Tower bonfire party has said his family is in danger after the video went viral.
Paul Bussetti is said to have been one of six men who handed themselves in at Croydon Police Station.
The men were all released under investigation on Tuesday evening, Scotland Yard said.
The video showed a large flammable model marked Grenfell Tower being set on fire, complete with paper figures at the windows.
Mr Bussetti, 46, and his family are now scared for their safety, a relative told Mail Online.
She said: Were in so much danger now. They didnt want it to go this far. They are not racist. Its been blown out of proportion.
It was horrible what theyve done. Let them try and forget it.
The six men – two aged 19, two aged 49, 46 and 55 – were arrested on suspicion of a public order offence.
In the clip posted online, raucous laughter can be heard off camera as the effigy is set alight.
A person can be heard saying: Didnt it start from the tenth floor, though?, while others add: Help me! Help me! and Jump out the window!
Another says: Here we go, as the fire takes hold.
At the end of the clip, someone else can be heard saying: Thats what happens when they dont pay their rent.
The video ends as the model is completely consumed by the fire, with one bystander saying: Perfect.
Campaigners described the video as a sickening act of hate.
Natasha Elcock, from Grenfell United, said: Its a disgusting video. We hope that the police are taking this seriously.
Justice4Grenfell said it caused great alarm and distress.
A total of 72 people perished as a result of the tragedy at the west London block on June 14 last year.
