Anastasiya Vaitsiakhovich was a defendant in the case of the attempted arson of the house of Aleh Haidukevich, a pro-government parliament member (allegedly, on the night of July 11-12, 2021, his house was attacked with Molotov cocktails). She was arrested together with her husband and his parents (see below).

According to the indictment, from July 14, 2020, to January 6, 2022, "an organized criminal group was created and operated on the territory of Belarus, Turkey, Poland, Ukraine, and other states, with the main purpose to commit an unspecified number of extremism-oriented crimes. The crimes were to be carried out by persons who are radically inclined towards the current government, including former military personnel, law enforcement officers, primarily those from the special forces units, hand-to-hand combat athletes, businessmen, and others who shared the views of the seizure of state power by unconstitutional means".

On June 21, 2023, the Minsk City Court announced the verdict. There were 18 defendants in the case, 15 of whom were in custody, and three were convicted in absentia. The trial lasted for four and a half months. Judge Siarhei Khrypach sentenced Anastasiya Vaitsiakhovich to 11 years of imprisonment in a general-security penal colony.

17 more political prisoners were convicted in the case: Vadzim Prakopyeu, Ihar Chamiakin, Dzianis Khamitsevich, Siarhei Lisouski, Piotr Yurkevich, Pavel Chykhinski, Dzianis Filonchyk, Vital Vaitsiakhovich (father), Volha Vaitsiakhovich (mother), Uladzislau Vaitsiakhovich (son), Uladzimir Saviankou, Dzmitryi Neviarkevich, Volha Piatukh, Mikalai Roi, Siarhei Sakalou, Eduard Piastrak, and Aliaksei Mikhailau.
