Police are hunting 13 people after at least five officers were seriously injured in clashes with protesters outside the Iranian embassy in central London on Sunday.
Twelve arrests were made after “missiles” including bottles and masonry were allegedly thrown by the large crowds gathered at Princes Gate in Kensington, Marble Arch and at the Islamic Centre of England in Maida Vale.
The protests follow the death of Mahsa Amini - the 22-year-old woman who died in police custody in Iran after being arrested for breaking the country’s hijab laws.
Large gatherings had taken place around Princes Gate - which borders Hyde Park - for several days and all had been “largely good natured”, the Metropolitan Police said.
However, on Sunday, “a significant group” confronted officers and other protesters from groups they were not aligned to.
In one video, an angry protester is shown being tackled to the floor after breaking through police lines to get to the embassy.
Commander Karen Findlay, responsible for the Met’s Public Order Crime Team, said: “Everyone who plans and seeks to lawfully protest, and communities in the vicinity of such protest, deserve to feel safe.
“Nobody should be faced with the escalation of disorder we saw on Sunday.
“We won’t tolerate members of the public, or officers who are doing all they can to maintain and regain order, being injured in any circumstance, and we are now doing everything we can to make sure those who committed the violent offences are brought to justice.
“This begins with identifying those with the blatant intent to cause injury by recklessly throwing items including pieces of masonry and bottles.”
Officials say some 35 people have been killed since protests broke out over the death of Ms Amini in police custody.
Women have taken a prominent role in the street protests, challenging the country’s Islamic dress code and waving and burning their veils.
