In August 2020, during the post-election protests, the then underage Fiodar left comments in the Telegram channel "Borisov-97%". According to the prosecution, in them he called for killing Lukashenko and "taking" the local executive committee, and also posted an image of a "Molotov cocktail".
In March 2022, Fiodar was found guilty in a criminal case brought under the article "Organisation and preparation of actions grossly violating public order, or active participation in them" and sentenced to restricted freedom without referral to an open-type correctional facility ("home chemistry").
