Sergey Viktorovich Eremeev

On December 9, 2023, a court in Omsk remanded Sergei in custody until January 30, 2024, on charges of blowing up trains carrying oil products in the Severomuysky Tunnel on November 29 and 30. The train, carrying 41 fuel tankers, three aviation fuel tanks, and six cars carrying ferrous metal, first caught fire. Later, a freight train traveling along a bypass route was blown up. As a result, the fuel spilled over an area of 150 square meters—four fuel tankers were completely destroyed, and two more were damaged. According to the FSB, Yeremeyev "confessed to working under the control of Ukrainian special services." The tunnel explosions were classified as a terrorist attack.

According to Russian state media, Yeremeyev claimed he wanted to interfere with the delivery of military supplies: "I wrote in my explanation that ammunition was currently being transported across the Baikal-Amur Mainline. The main goal was to impede traffic."

Sergey participated in the nationwide strike at Naftan in November 2020, which he publicly stated and even sent a statement to Tikhanovsky's movement. "Sergey tried to resolve everything peacefully. Maybe he was tired of nothing being resolved... in the video, even though his face was painted over, I recognized him immediately," an acquaintance of Yeremeyev said . A few weeks after the strike, Sergey was fired from Naftan. Sergey was one of the best mechanics in Novopolotsk.

According to investigators, in November 2023, Yeremeyev secretly transported explosive devices across the Russian border in his vehicle and arrived in Buryatia. Then, with the intent to commit a terrorist act, he planted explosive devices at night on a section of the East Siberian Railway and on trains traveling along it, activating the remote controls. The court ruled that the detonation of the explosive devices planted by Yeremeyev caused property damage to the victims, related to the destruction and damage of tank cars and railway equipment, amounting to over 100,000,000 rubles ($1.2 million), as well as other serious consequences in the form of disruption of the operation of a federal transport highway.

The court sentenced Yeremeyev to 22 years in prison, with the first five years to be served in a maximum-security penal colony, and a fine of 1,000,000 rubles. Yeremeyev's vehicle was ordered confiscated. The court also upheld the victims' civil claims against Yeremeyev for damages totaling over 60,000,000 rubles ($744,000), which were ordered to be recovered from the convicted person.
