Anti-lockdown protesters have surrounded police officers and started hurling smoke bombs in central London.

The group broke through a police barrier in central London and are making their way down Oxford Street.

Daily Mirror journalist Matt Capon tweeted: "Pretty chaotic scenes. The police tried - and succeeded for a short time - in splitting up the crowds and ordering people to disperse.

"However, they've now formed up again and are now marching down Oxford Street."

A large group of demonstrators chanting "freedom" left Hyde Park near Marble Arch and marched along a road parallel to Oxford Street.

The Metropolitan Police had earlier warned people to avoid the rally.

The force said in a statement: “Protest is not currently a permitted exemption to the prohibition on gatherings under the current coronavirus regulations.

“Strict regulations have been introduced by the government nationally to help prevent the spread of coronavirus. This means that anyone gathering for protest risks enforcement action by officers.”

Anti-lockdown protest groups called for supporters to travel to Kings Cross, London, this morning.

Police officers gathered as the protest kicked off

By 11am, the location had been changed after police made a number of arrests of people arriving at the station.

Footage emerged on social media of officers appearing to arrest a man who is heard screaming as he kneels on the pavement.

Previous demonstrations have attracted tens of thousands of people.

Ch Supt Stuart Bell said: “This type of behaviour not only breaks the law, it also risks spreading the virus between multiple areas of the country.

"It is for this reason that we urge people not to travel into London and this is also why we will be taking appropriate enforcement action if this happens.”
