Three Greenpeace protesters from Devon are back in the country after being imprisoned for two months in Russia.
Cameraman Kieron Bryan, together with Alexandra Harris and Iain Rogers were part of a 30-strong group arrested at a protest against Arctic oil drilling.
The three arrived in the UK today after being granted exit visas. They say it was possibly to avoid bad publicity in the run up to the Sochi Winter Olympics.
WARNING, FLASH PHOTOGRAPHY:
Freed Greenpeace activist Alexandra Harris said her time in Russian prison "was torture", but that she and others jailed after Arctic protests were "treated better than the Russian prisoners, because the world's watching us".
"We spent two months inside a Russian jail cell and a hundred days detained for a crime we didn't commit," Harris said. "It was obscene, a complete overreaction on behalf of Russia and we should never have been there."
