Yegor Dudnikov is a Russian citizen. He had lived in Minsk for about a year before being detained. In Minsk, he earned money as a voiceover actor and narrator in cartoons, anime, games, and commercials. He also works as a video editor.

Dudnikov was detained on May 4, 2021, in Minsk. His rented apartment was searched (only one microphone was confiscated) and the detainee was placed in the KGB pre-trial detention center. He was beaten during the detention.

Dudnikov was charged under Part 1 of Art. 342 of the Criminal Code (organization of actions grossly violating public order) for which he faces up to three years in prison.

The detainee was later transferred to SIZO-1 in Minsk.

According to the investigators, from January 19 to May 21, 2021, with the help of computer equipment, in order to escalate tensions and conflicts in society and the state, Dudnikov posted in a Telegram chat at least 55 "provocative messages". By doing this, he "incited social hostility and discord on the grounds of professional affiliation, formed a negative image of the authorities and hostility to them, inclined citizens to take part in illegal protests." He also called to "seize state power", "forcibly change the constitutional order," provoked "mass riots with violence against government officials," as well as other actions "to the detriment of the country's national security."

On December 27, the Minsk City Court announced a verdict in the criminal case against Yegor Dudnikov. Judge Siarhei Khrypach sentenced Yegor to 11 years in a medium-security penal colony, just as the prosecutor Zhanna Baranava requested.

On February 25, 2022, the judge of the Supreme Court Ihar Liubavitski reviewed Yegor's appeal and upheld his sentence.

On June 15,  2022, the Court of Babrujsk and Babrujsk District raised Yegor's custody level. Judge Pavel Karcinin ruled to transfer him from a medium-security penal colony to a prison. 

On July 8, 2023, it was announced that Yegor had been transferred to prison No. 4 in Mahilioŭ.
