Five men have been arrested on suspicion of a public order offence in connection with a model of Grenfell Tower being burned on a bonfire.
A video shared on social media shows a cardboard model of the tower being set alight by a laughing crowd.
The Metropolitan Police said the men - two aged 49 and the others aged 19, 46 and 55 - handed themselves in at a south London station on Monday night.
Prime Minister Theresa May had called the video "utterly unacceptable".
The men have been arrested under
section 4a of the Public Order Act 1986, which covers intentional "harassment, alarm or distress" caused via the use of "threatening, abusive or insulting" words or signs.
Offences committed on a private residence where a person "had no reason to believe" it would be "heard or seen by a person outside that or any other dwelling" are protected from prosecution under the act.
Racially or religiously aggravated offences under the act carry a prison sentence of up to two years, a fine or both.
