In the center of the Russian capital on Red Square, at least 10 activists who read aloud the text of the RF Constitution, were detained, Radio Liberty informed.

Reportedly, a well-known Russian activist Ildar Dudin was among the detainees. He became the only person in Russia, convicted and imprisoned under penal provisions on repeated violations of the rules for holding mass events.

Police draws administrative protocols on detained activists over violation of the established public order.

If they are found guilty, they will face a fine of 10 to 20 thousand rubles or forced labor for up to 40 hours.

Ildar Dadin repeatedly held peaceful protests against Russian President Vladimir Putin without official permission. He was sentenced to imprisonment in December 2015 under an article providing for criminal liability for participation in more than one unauthorized action within 180 days. In February 2017, the Supreme Court of Russia quashed his sentence and closed the case.
