Stanislav was arrested in September 2021 as part of a criminal case opened following spontaneous protests that took place in Brest from August 10 to 11, 2020, against the falsification of the presidential elections.
In January 2022, he was convicted of participating in "mass riots" and sentenced to imprisonment in a maximum-security penal colony. He was accused of intentionally breaking paving slabs while preparing "instruments of crime." He was also charged with causing physical harm, in the form of two wounds to the thumb of Igor Kalyagin's right hand, and "beating" other victims.
He was released in the summer of 2024, having fully served his sentence.
