Konstantin was arrested on May 12, 2021, for participating in a work Telegram chat called "Volnae Panstva," where he and colleagues discussed the protests and made comments about Lukashenko. He was sentenced to administrative arrest, after which he remained in custody, as a criminal case had been opened against him for group actions grossly violating public order and for the use of violence against a law enforcement officer.
In September 2021, Konstantin was found guilty of three criminal charges for participating in a post-election protest that took place in Rechitsa on August 9, 2020. He attempted to prevent the arbitrary detention of protesters and, as police were loading the detainee into a police vehicle, pushed Rechitsa police officer Dmitry Garay in the back. He was also charged with insulting Lukashenko.
He was released in February 2024, having fully served his sentence.
After his release, Konstantin was again subject to administrative charges for missing an ideological lecture. He subsequently left Belarus.
