A group called Extinction Rebellion targeted the Anglo-Dutch oil major as part of a days-long event in which it disrupted public areas throughout London with banners and props. Earlier this month, several Extinction Rebellion activists stripped semi-naked in the House of Commons during a Brexit debate.
Workers at Shell were prevented from leaving the building after members of Extinction Rebellion superglued themselves to the entrance of their office, just before lunchtime too.
Protesters will gather at Marble Arch, Oxford Circus, Waterloo Bridge, Piccadilly Circus and Parliament square, peacefully blocking traffic and creating a "festival" of action including people's assemblies, speeches, performances, workshops and food. Police arrested 85 activists that day and organizers say they expect further arrests on Monday.
At least, Waterloo Bridge was unwittingly pedestrianised.
More than 100 Norwich branch members of environmental group Extinction Rebellion's travelled to London today to block five of the cities busiest roads and demand government action on climate change.
The protest had a festive atmosphere, with many families in attendance, and a low police presence. They plan to engage in acts of non-violent civil disobedience against governments in capital cities around the world.
'No arrests have been made in connection with the protest'. This crisis is only going to get worse Prime minister, you can not ignore this crisis any longer. Organisers of the protests circulated legal advice to anyone planning to attend, requesting they refrain from using drugs and alcohol, and asking them to treat the public with respect.
"In London, people are willing to be arrested and to stay".
Police have advised Londoners to leave extra time for their journeys because of possible delays caused by the protest.
A spokesperson for Extinction Rebellion said: "Ordinary citizens, terrified by the threat we all face to our future, will risk arrest and imprisonment by blocking bridges, roads, harbours and transport systems".
