The couple, identified as Igor R. and Irina R., were arrested in July 2024 and have remained in custody since. They face charges of espionage under Article 130 § 2 of Poland's Criminal Code, which covers crimes that could harm national interests.
Investigators say Igor R. worked with the FSB from February to August 2022, gathering and passing on sensitive information.
He collected details on Russian opposition figures living in Poland, as well as the people and organizations supporting them. Igor encrypted the data and sent it to his wife on electronic storage for relay to the FSB.
From Russia, Irina R. tried to deliver the information by mailing the encrypted data through a parcel locker and seeking direct contact with FSB representatives.
Igor R. also faces additional charges for helping send a courier package containing explosives in July 2024, alongside two Ukrainian citizens and another Russian. Experts from Poland's Internal Security Agency (ABW) determined the package held powerful explosives, in particular nitroglycerin, Soviet-era electric detonators, a modified power bank used as a trigger, a metal thermos with a shaped charge, and a bag of powdered aluminum.
Prosecutors said the setup formed a shaped-charge bomb that could have caused major infrastructure damage if detonated.
The package was found at a courier warehouse in Poland's Lodz Voivodeship. Ukrainian citizen Kristina S., who tried to send it, was indicted on June 30 and convicted on Aug. 21 under a Criminal Code statute covering the organization of a "dangerous event."
Materials on other suspects have been spun off into a separate ongoing probe, conducted jointly with the ABW's Katowice branch.
In a related case, an Estonian court earlier convicted Russian soldier Ivan Dmitriev of intelligence activities for Russia, sentencing him to four years and 11 months in prison plus a 2,215-euro ($2,561) fine.
