Extinction Rebellion: police warn of Parliament Square arrests

Order targeting the protest is first to explicitly mention organisers could be detained

Police have warned Extinction Rebellion organisers that they face arrest if they incite protesters to block roads around Parliament Square.

The Metropolitan police said it was imposing pre-emptive conditions restricting any demonstration outside the Houses of Parliament on Tuesday to the lawn in the centre of the square, after hearing that activists with the group planned to gather there.
