Kirill was convicted of "participating in group actions that grossly violate public order" in a criminal case opened after a protest that took place in Brest on September 13, 2020. At that time, the participants were singing and dancing in circles, and a water cannon was used against them. According to the prosecution, the action disrupted the operation of public transport.
Before he began serving his sentence, he left Belarus.
In December 2024, it became known that a court hearing in absentia was held regarding Kirill to replace the restriction of freedom with imprisonment in a penal colony.
