"We've found Zakhar, the hero who waved a Ukrainian flag over Moscow State University on the third anniversary of Crimea's annexation. A wonderful interview ended with the arrival of the police.

He wrote later: "We have been detained and are being taken to a local police station to check the "legality" of the shooting. This is my first ever trip in a police car:) The accreditation of the Russian Foreign Ministry did not help."
