Environmental campaigners Greenpeace today closed down a number of petrol stations in Edinburgh. This footage from The Greenpeace website shows the moment they first targeted two Shell petrol stations in Edinburgh in a protest against the company's plans to drill in the Arctic region. The Save the Artic banners are all over the site. Activists use the emergency shut-off switch, which stops petrol going to the pumps, to close the station. Protesters could be seen on the roof of the Shell station in Dalry Road early on Monday morning, and a man in a polar bear outfit chained himself to a pump before being cut free and led away by police.
