'Polar bear' floats past Kremlin in Greenpeace protest Tuesday 2nd April 2013 | Osh A Greenpeace activist in a polar bear suit floated along the Moscow River past the Kremlin on Monday morning before being briefly detained in a stunt by the environmental group to protest against energy exploration in Russia's Arctic waters. The activist in a furry white suit stood on a white air cushion designed to look like an ice floe with signs reading "Help!" and "Arctic not for Sale" before a river patrol came out in a motorboat and bundled the activist inside. The activist was later released from a police station with no charge, Greenpeace said on Twitter, adding that "the crimes are being committed in the Arctic." Greenpeace said the protest aimed to draw attention to a planned joint venture between Norway's Statoil and Russia's Rosneft to explore Russia's Barents Sea for untapped oil reserves.
