London, UK. 20th April 2019. Police officers use cutting equipment to remove climate change campaigners from Extinction Rebellion who had locked themselves using arm tubes at Oxford Circus following a policing operation to clear it of protesters earlier in the day. The heart of London’s shopping district was blocked again for around two hours by the lock-ons on the sixth day of International Rebellion activities to call on the British government to take urgent action to combat climate change.
