Crowds of left-wing campaigners clashed with cops on a London estate as police conducted an apparent raid to detain illegal immigrants.
More than 100 protesters gathered in Peckham, south London this afternoon in an attempt to halt the raid.
They chanted as cops took one man: 'Let him go!'
Campaigners tweeted videos of the protest with the caption: 'Come and join us.'
Nunhead & Queens Road councillor Reginald Popoola wrote: 'I’m here with over 100 others.
'Block the van from taking one of our neighbours - come and join us now on Evan Cook Close SE15!'
Brighton's anti-Israel Boycott, Divest and Sanction campaign Twitter account wrote: 'Solidarity to community resisting immigration raid right now in Peckham. More numbers needed.'
Other chants sung by the crowd included: 'You say people, we say power, people power.'
Police arriving and trying to violently remove a peaceful protest on a public right of way.
Southwark Labour councillor and primary school teacher James McAsh tagged the Camberwell and Peckham Constituency Labour Party and Southwark Momentum.
He wrote: 'URGENT - Immigration raid in Evan Cooks Close, Peckham, Se15. Near Queens Road station.
'Currently being blocked by a big crowd. Get down ASAP. Please RT or pass on the message.'
The raid appears to have started shortly after midday, with crowds assembling over the next two hours.
Tweets shared by local campaigners and councillors raised awareness about the event.
It's not clear whether the protest has stopped the police from detaining any of the immigrants they are thought to be searching for.
MailOnline has contacted the Metropolitan Police for comment.
The revolt came as the first Home Office flight to Rwanda was set to go ahead on Tuesday.
The plans survived a bid by left-wing lawyers to halt the policy as a violation of human rights legislation.
A High Court judge last night threw out a bid to halt the first charter flight to Rwanda.
Mr Justice Swift said he had to balance the concerns of individual migrants with the wider public interest.
Prince Charles reportedly joined the opposition, claiming the Rwanda plan is 'appalling'.
A union representing Border Force staff and two charities claimed in the High Court yesterday that Rwanda was an unsafe country and Miss Patel was exceeding her powers as Home Secretary.
But rejecting their application for a temporary injunction blocking next week’s first flight, Mr Justice Swift said: ‘It is important for the secretary of state to be able to implement immigration control measures, and preventing that would be prejudicial to the public interest.’
Responding to the ruling, Mr Johnson said: ‘Welcome news from the High Court today. We cannot allow people traffickers to put lives at risk and our world-leading partnership will help break the business model of these ruthless criminals.’
The coalition that brought yesterday’s legal challenge was granted permission to appeal to the Court of Appeal.
That hearing is expected on Monday.
