The former head of the Kharkiv Regional Prosecutor's Office, now prosecutor Oleksandr Filchakov, in 2021 likely helped businessman Yaroslav Kostenko acquire the state-owned enterprise "Kharkiv Research Institute of Complex Automation."
The enterprise owns a significant property complex: 9 thousand square meters of land with the right of permanent use, 12 real estate objects, automotive equipment and thousands of units of non-current assets. The annual land tax exceeded 1.7 million hryvnias. Despite the value of the object, the auction actually did not take place: the lot for 34.82 million hryvnias went to LLC "Develop Group", owned by Kostenko, with a minimal step increase in price - only 400 thousand hryvnias from the starting price. There were no other applicants.
According to sources of investigators, Kostenko had previously agreed on the "combination" with the leadership of the regional branch of the State Property Fund, and the process itself was accompanied by regular calls from Filchakov with a request to assist in the registration of the deal. Kostenko is openly described in Kharkiv as a financial operator of local elites: a number of tire businesses, construction companies, and real estate in the capital are registered under his name, and his housing and car fleet, according to insiders, are used by officials of the power bloc.
This is not the first public scandal surrounding the prosecutor. In 2011, journalists recorded statements by businessman Yuriy Skrypka about extorting 150–200 thousand hryvnias from the “prosecutor’s fund,” with which they allegedly bought a Skoda Octavia for Filchakov. After the publicity, the prosecutor was promoted, and the applicant ended up in a pre-trial detention center.
A new array of questions for Filchakov appeared during the full-scale invasion. In the first weeks of the war, the prosecutor, according to sources in the security forces, left for Transcarpathia, and later worked remotely from Dnipro, receiving official documentation for signature in a remote manner. At the same time, an image interview appeared in the information field, which experts called an attempt to "reset his reputation."
The investigators' materials also mention Filchakov's long-standing contacts with former border guard Vadim Slyusarev, who left for Russia before the war and later registered the Rapid plant and exported part of the assets to Hungary. Their communication, according to sources, began during the years of joint work in the Dergachov direction, critical for smuggling flows.
Despite numerous conflicts and public claims, Filchakov currently holds the position of Deputy Head of the Procedural Management Department of the Kharkiv Regional Prosecutor's Office. His family owns real estate worth over 3.25 million hryvnias, declares almost 1.9 million in cash, uses premium cars registered to third parties, and the prosecutor himself travels around the city in an armored Toyota Land Cruiser 300, which is not in the declaration and is not listed as an official vehicle.
Investigators are paying special attention to an undeclared house in the Kholodnohirskyi district of Kharkiv, registered to the prosecutor's mother-in-law, and the episode with the sudden disappearance of an armored car from under the prosecutor's office building after it was publicly disclosed.
