Greenpeace 'Arctic 30' activist Tomasz Dziemianczuk is met by his wife Natalia Bajorek-Dziemianczuk and his father as he arrives at Warsaw Okecie airport after being detained in Russia for over 100 days.
The 'Arctic 30' (28 activists and two freelance journalists) were arrested in September 2013 by Russian authorities following a peaceful protest at a Gazprom operated Arctic oil platform in the Pechora Sea.
