Students of colleges and universities in Russia have launched an anti-Kremlin "Putin is a Thief" challenge in support of a tenth-grader from Krasnoyarsk Krai after his history teacher threatened to call police for his writing "Putin is a Thief" on the blackboard.

The challenge started in the StalinGulag group of Vkontakte, a Russian Facebook-like social media, where a picture made at school No. 4 in Gusinoozersk in Buryatia, a mountainous Russian republic in eastern Siberia, appeared, Russia's Snob online magazine reported.

The challenge was taken up by students from Krasnoyarsk, Nizhniy Novgorod, Krasnodar.

In particular, a student from Krasnoyarsk wrote "Putin is a Thief" as the answer to a physics problem.

New participants continue joining in the challenge.

Media reported on November 12 that a student had written "Putin is a Thief" on the blackboard of school No. 20 in the village of Tayezhny in Russia's Krasnoyarsk Krai. History teacher Yevdokiya Kovalyova, who boasts of 60-year teaching experience, gave a lecture to the whole class, saying that it was worth calling police because of the incident. She also recalled the Soviet times when execution was selected as the punishment for such "crimes."
