Russia grants bail to four more Greenpeace activists Russian jails freed four more of the 30 people arrested following a Greenpeace protest in Arctic waters two months, after they posted bail, but the charges against them still stand. Bail already has been granted this week to 26 of the people who were on the Greenpeace ship the Arctic Sunrise and the bail hearings were to continue on Friday. The rulings by judges in St Petersburg could moderate the international criticism of Russia over the case. Free at last: David John Haussmann of New Zealand gestures after being released on bail from prison in St. Petersburg. Brazilian activist Ana Paula Alminhana Maciel, who was released late on Wednesday, was the first to walk free, followed on Thursday by three Russian citizens and a crew member from New Zealand. The Brazilian activist's lawyer, Sergei Golubok, said Maciel was free to move about St Petersburg and was given back her passport, but she "is not going to leave Russia before the situation is cleared up." As a Brazilian, Maciel does not need a visa to be in Russia, but many of the other foreign activists would need a visa to remain there legally. Reunion: Photographer Denis Sinyakov of Russia embraces his wife Alina after being released from prison. It was not clear what arrangements would be made or if they would be allowed to leave the country. "We don't know yet if they will be able to leave the country," said Patric Salize, a Greenpeace spokesman in St Petersburg. We need to figure that out with the Russian authorities. All of those detained were initially charged with piracy, but investigators later changed the charge to hooliganism, which, although a lesser charge, carries a potential sentence of seven years. Piracy's maximum is 15. Bail for each of those released has been set at two million roubles ($A66,000). "Our case is not closed yet," said activist Andrei Allakhverdov, one of the three Russians released on Thursday. We will fight for the case to be closed and for us to be found not guilty. The two other Russians freed were ship doctor Yekaterina Zaspa and photographer Denis Sinyakov. David John Haussmann of New Zealand also walked free. Australian radio operator, Colin Russell, whose bail hearing came up first on Monday, was ordered to remain in custody until February. A Greenpeace lawyer says an appeal will soon be filed seeking to secure his release as well, according to the RIA Novosti news agency. The 30 were arrested in September after the Arctic Sunrise entered Arctic waters despite Russian warnings and some of the activists tried to scale an offshore drilling platform owned by the state natural gas giant Gazprom. Greenpeace contends Arctic drilling poses potentially catastrophic environmental dangers, but Russia bristles at criticism of its oil and gas industry, which is the backbone of the country's economy.
