The Prosecutor General's Office along with the Security Service of Ukraine documented new facts of a leak from the National Anti-Corruption Bureau of Ukraine of confidential information related to the Bureau's activities.

As part of the investigation into the suspicion of Ukrainian MP Fedor Khrystenko (representative of the banned party "Opposition Platform — For Life" (OPZZh)) in treason, during searches of the residence where his close relatives currently live, materials of covert investigative actions against persons involved in criminal proceedings under NABU proceedings, as well as dozens of personal profiles of candidates for the positions of detectives of the Bureau, were seized. Among them are cards with data on individual current and former NABU employees.

It was established that among the documents is the personal file of one of the heads of the NABU interregional detective department, Ruslan Maghamedrasulov. According to the investigation, he had contacts with representatives of the aggressor country and facilitated illegal foreign economic activity related to the Russian Federation. Also, the questionnaire of former NABU detective Timur Arshavin, who in 2024 left the territory of Ukraine outside the established checkpoints, was found.

It is reminded that on July 20, 2025, Fedor Khrystenko was notified in absentia of suspicion of high treason committed under martial law by a group of persons in a preliminary conspiracy (part 2 of Art 28, part 1, part 2 of Art 111 of the Criminal Code of Ukraine), as well as abuse of influence (part 2 of Art 369-2 of the Criminal Code of Ukraine).

According to the investigation, Khrystenko was recruited by representatives of the Russian special services during the regime of Viktor Yanukovych. He maintained ties with former functionaries of the so-called “DPR” and was in contact with representatives of the Russian Federal Security Service.

According to the investigation, this concerns possible assistance in the escape abroad of one of the persons involved in large-scale economic crimes, in particular, the business partner of Ihor Kolomoisky.
