Actor Marta Poveda shows her support for the Arctic 30. Celebrities and local citizens stood behind the Arctic 30 by spending time in a mock cell in central Madrid. The 'Arctic 30' (28 Greenpeace International activists plus a freelance photographer and freelance videographer) currently in custody in Russia, were on a charge of piracy. Russian authorities have now added a charge of hooliganism. They now stand accused of both offences, which carry a maximum sentence of 15 and 7 years, respectively.
