Free the Arctic 30

This is from Greenpeace asking for action on the Arctic 30. Please help.

Right now, 28 of our activists, a photographer and a videographer are being held in custody by the Russian authorities. We urgently need your help to free them.
The Arctic Sunrise had been part of a peaceful protest against energy giant Gazprom, which is poised to drill for the first oil to come out of the icy waters of the Arctic.
Using a helicopter and ropes, armed Coast Guards illegally boarded the ship and held those on board under armed guard whilst they towed the ship to shore. Our team were then remanded for up to two months by a court in Murmansk.
The authorities say they need time to investigate possible charges of piracy - even though President Putin has said that he did not believe they were pirates.
Please send an urgent email to the Russian Ambassador in London and demand the immediate release of these peaceful protestors.
