Colin Russell, the last detained Greenpeace activist in Russia of the 30-member crew, has been granted bail on Thursday.

The Australian was detained in Russia along with the rest of the crew in September. The Greenpeace activists were protesting against Arctic oil drilling. An earlier ruling extended the period of Mr Russell's detention in the country. He was asked to remain in pre-trial detention until Feb 24. The latest court ordered reversed the earlier one and released the radio operator of the Arctic Sunrise.

An ecstatic post on Twitter by the global environmental protection group confirmed the release, Sky News reports. Russian news reports too confirmed the Saint Petersburg court order. While Russian President believes the first oil rig in the Arctic is the future of energy export for the country, the Greenpeace thinks that it is extremely dangerous for the environment.

The Greenpeace activists were initially accused of piracy by Russian authorities. However, the charges against the activists were made less stern as they are blamed of hooliganism later on. Now that Mr Russell's detention has been withdrawn, some analysts predict that the Russian government intervened and asked the judicial authorities to maintain an easier approach.

Christine Russell, Mr Russell's wife, expressed her relief caused by the court order. She called her husband a 'peaceful man' and said that she was relieved to know that he would be out of detention shortly. Ms Russell also said that the proper celebration would only take place when all of the Arctic 30 members were set free. The Arctic 30 comprised of members from 18 different countries, except Russia. If the charge of hooliganism is proved against them, they may be sentenced for seven years. It is yet to be known when the rest of the member will be allowed to go home.

A Greenpeace official Ben Ayliffe said that the struggle was not over as the activists were still accused of a criminal activity which they had not committed.
