Apparently, he was arrested, and fined, for trespassing at the Baikonur Cosmodrome [1], in Kazakhstan, which is leased to Russia. Then, he was then arrested and “found guilty of committing an administrative offense under Part 1 of Art. 20.3.3. Code of Administrative Offenses, that is, in discrediting the Russian Armed Forces.” [2]. The first offense seems to have occurred a few months ago. What he says is interesting regarding YouTube, etc.
