Extinction Rebellion protesters block Oxford Circus in London

Female activists claim police officers trampled them as they rushed to secure cordon

Extinction Rebellion protesters have blocked Oxford Circus in London, the site of one of the group's most famous occupations, as women took the lead on the third day of its latest campaign of disobedience.

Just before 2pm, protesters swarmed into the middle of the intersection between Regent Street and Oxford Street, London's busiest shopping district, and erected a pink structure and sound system.
