The Specialized Anti-Corruption Prosecutor's Office (SAPO) has registered a criminal proceeding to investigate into a possible disclosure of data of the pretrial investigation in the criminal proceedings against Ukrainian Infrastructure Minister Volodymyr Omelyan, who is suspected of unlawful enrichment, by Director of the National Anti-corruption Bureau of Ukraine (NABU) Artem Sytnyk.

"It is a question of yesterday's [September 20] statement of suspected Infrastructure Minister of Ukraine Volodymyr Omelyan about the advance notification of him by the specified official about the planned search of his place of residence," the SAPO said on its Facebook page on September 21.

It is reported that this statement by the minister "is not considered unsubstantiated, since the materials of the criminal proceeding in which he was informed of suspicion contain information about the presence of telephone connections between Omelyan and the subscriber recorded as "Artem Sytnyk," on the eve of the search," in particular, four calls on November 2, 2017 were made.

"To ensure the effectiveness of pretrial investigation, the materials of the criminal proceedings will be sent to the Prosecutor General to determine the body of pretrial investigation," the SAPO reported.

"At the same time, we draw your attention to the fact that Sytnyk consistently and regularly implements unlawful disclosure of these pretrial investigations, which significantly harms the interests of criminal proceedings," the SAPO reported.
