Ihar Tsiaptseyeu was sentenced on June 15, 2023 in the Minsk City Court under Part 1 of Article 368 of the Criminal Code (insulting Lukashenka), Part 2 of Article 339 of the Criminal Code (hooliganism), Part 2 of Article 361-4 of the Criminal Code (promoting extremist activities), Article 361-2 of the Criminal Code (financing the activities of an extremist group). The case was considered by the judge Vera Halaukova.

Yury Nestsiarenka, Ihar Tsikach, Uladzimir Savelyeu, Viktar Hrynko were convicted together with Tsiaptseyeu on that day.

On September 14, 2023, the judge Edgar Martsirasyan heard an appeal against the sentences.

In late October 2022, the men were arrested in Minsk for allegedly hanging a white-red-white flag together with the flag of Ukraine on power poles in Minsk on October 7. A post with a photo of the flag and the caption appeared in the Telegram channel the next day. The caption said: "The citizens of Minsk congratulate the people of Ukraine on the wonderful news from the bridge in Crimea. Crimea is Ukraine! Long live Belarus! Glory to Ukraine!".

In the pro-government film Tsiaptseyeu told that he had known the other defendants in the case since childhood. According to Ihar, he didn't think that there would be criminal responsibility for hanging the flags. 

According to the propagandist Gladkaya, Ihar's wife was forced to leave Belarus because of persecution for the events of 2020. Now she is in Poland, while the man and their small children were left in Belarus.

It is known that Ihar was sentenced to three years and six months of imprisonment.

      On October 20, 2023, the Ministry of Internal Affairs added Ihar to the "list of extremists".
