According to Ukrinform, the SBU said this in a statement.

The suspect is a National Guard officer who commanded a special operations group.

The investigation found that the officer had been passing Russian invaders classified information about his unit's combat operations both on the front line and behind enemy lines.

In particular, the officer "leaked" classified information from the National Guard's secure information system to the Main Directorate of the General Staff of the Russian Armed Forces, commonly known as the GRU. To do so, he provided Russian intelligence officers with the credentials needed to access his personal account on the agency's internal online platform.

The Russians hoped to use this access to remotely obtain classified information about the planning, preparation and execution of combat operations, as well as command procedures for personnel in the special forces unit.

The SBU said it began documenting the suspect's activities at an early stage of his intelligence operations.

He was detained at his home in Odesa after additional measures were taken to protect the security of Ukrainian forces' operations.

Investigators also established that, at the request of Russian military intelligence, the suspect set fire to a military vehicle in the port city and recorded the fire on his phone.

According to operational intelligence, the "mole" was subsequently expected to assemble an improvised explosive device and hand it over to a "courier" to carry out a terrorist attack in southern Ukraine.

During searches, law enforcement officers seized a smartphone, laptop and other data storage devices containing evidence of the suspect's cooperation with Russian military intelligence.

Investigators charged the officer under Part 2 of Article 111 of Ukraine's Criminal Code – high treason committed under martial law.

The suspect is being held in custody without the possibility of putting up bail. He faces life imprisonment with confiscation of property.
