A resident of Kemerovo, who host a blog on YouTube titled "Don't Be Inert", which is dedicated to exposing violations by officials and law enforcement. On April 28, 2020, he, along with his co-host Sergey Kamensky, participated in a raid against illegal parking. A conflict arose between the activists and the driver of one of the parked cars. According to the investigation, Lavrentyev sprayed pepper spray towards the driver. However, according to a video published by the bloggers' supporters, it was not Lavrentyev but Kamensky who sprayed the driver with gas when the driver attacked him. Later, an unknown man attacked Lavrentyev, knocking him to the ground. On June 5, Lavrentyev, along with Kamensky, was filming a report near the Kemerovo FSB building. They approached one of the cars and demanded that the driver re-park. The car drove away, but a man in a suit emerged from the building, approached Kamensky, and, without introducing himself, asked, "Who are you?" then grabbed Kamensky's camera and quickly walked away. Lavrentyev chased him, trying to retrieve the camera, and sprayed gas from a canister several times in his direction. It was later revealed that the attacker was Dmitry Kislyov, an employee of the Kemerovo FSB. In June, in connection with the first incident, Lavrentyev was charged with hooliganism. On June 28, he was taken into custody. On July 13, he was placed under house arrest, but on August 7, he was taken back into custody because his common-law wife, who is a witness in the case, visited him during his house arrest (neither Lavrentyev nor she knew about this at the time). On October 5, Lavrentyev was charged with using violence against a government official due to the incident involving the FSB employee. In February 2021, Lavrentyev was also charged with inciting hatred as a member of an organized group created to discredit law enforcement. It was later revealed that Lavrentyev was also charged with intentional infliction of bodily harm out of hooligan motives with the use of a weapon and assault. Lavrentyev and his lawyer are under a non-disclosure agreement. Since March 2023, Lavrentyev has been held in a basement cell; a week ago, he was moved to another one, but he has been kept in solitary confinement the entire time. This has affected the blogger's psychological state as well as his health: Lavrentyev has developed a chronic illness and suffers from back pain due to drafts. During the last session at the Central District Court, an ambulance was called to administer an anti-inflammatory injection to Lavrentyev. On that day, January 24, the audience was not allowed into the courtroom, although the case is being heard in an open session. On August 16, 2024, Lavrentyev was sentenced to nine years in a penal colony.
