Well, by now on you've read the article by Belapan where you saw the quote that arrest was made based on the Interpol warrant by request of Azerbaijan. Belapan is independent news agency, at least they claim so on their website. It's not state owned, Belta is. How is my evidence is partial then?

P.S. Also he's a blogger, not journalist. And the story of Belarusian jail that OP referring to is full of shit, even some Belarusian opposition members who spent some time there, not few days like this guy, wrote in comments to the article that he wrote mostly bullshit. Of course it's not a resort, and for someone who got there first time it can be tough and shocking, but it's not as bad, as he describes.
