A court in Russia's second city of Saint Petersburg on Monday released on bail one of the 30 Greenpeace crewmembers arrested for an Arctic protest, the first of the activists to be set free, the group said. Yekaterina Zaspa, a doctor with Greenpeace's Arctic Sunrise icebreaker, was released on bail of two million rubles ($61,400), the group said, citing the ruling of Saint Petersburg's Kalininsky court.
