Kyiv Court Closes Treason Case Against NABU Detective Viktor Husarov

A Kyiv Court has closed a criminal case against National Anti-Corruption Bureau of Ukraine (NABU) detective Viktor Husarov, dropping treason charges and releasing him from liability over unauthorised access to data due to the expiry of the statute of limitations.

According to a spokesperson of the Prosecutor General’s Office, Maryana Hayovska, prosecutors refused to pursue the charges in Husarov’s case and submitted a motion to the Shevchenkivskyi District Court in Kyiv to close the criminal proceedings.

“Given the nature of these actions and the circumstances of the information transfer to his former colleague – a law enforcement officer who left for the temporarily occupied territory of the Autonomous Republic of Crimea in February 2014 – the investigation also checked a version regarding possible high treason,” Hayovska said, explaining Husarov’s position.

However, there was no sufficient evidence of intent to transfer the specified information specifically to any representative of the aggressor state. 

“In this regard, the prosecutor made the legally prescribed decision to close the proceedings” she added.

Husarov’s lawyer, Olena Storozhuk, told Ukrinform that “the proceedings are completely closed in terms of treason.” 

From “FSB Mole” to closed case

Husarov was one of the several NABU detectives accused of being tied to Russia, during a broader conflict between the bureau and the presidentially controlled law enforcement agencies, with many critics pointing out the pressure on Ukraine’s main anti-corruption body.

The Most and Least Likely American Voter to Support Ukraine

US public support for Ukraine remains resilient despite reduced military aid, with 54% of Americans considering the war personally important. Confidence in Trump’s handling of the conflict has dropped sharply to 32%, while 50% trust Zelensky. A notable age divide exists – older Americans are consistently more concerned than younger ones. Russia’s influence strategy is also evolving, increasingly leveraging internet personalities like Candace Owens and Andrew Tate to reach younger audiences.

In July 2025,  the Security Service of Ukraine (SBU) announced that it had detained an employee of NABU’S central office who worked in an elite, closed unit “D-2” and allegedly collected data of Ukrainian security forces and other citizens for FSB, who possibly used the information to plan terrorist attacks and other operations. 

As part of the investigation, it was established that the suspect transmitted information regarding Ukrainian citizens obtained from the Interior Ministry databases, UNN reports. 

According to these materials, Husarov received instructions from Dmytro Ivantsov, a former deputy to ex-President Viktor Yanukovych’s security chief who later fled to Russian-occupied Crimea.

Investigators pointed to at least 60 episodes of data transfer. At the same time, the defense argued that much of the information was already public, with screenshots of their correspondence having been taken out of context.

Husarov was presented as a part of a larger Russian intelligence network, that also included former SBU Major General Valerii Shaitanov, Ivantsov, and an unnamed National Guard serviceman.
