FSB officers identified a network of agents of Polish intelligence services in the Kaliningrad region and arrested two people who worked for the Polish military intelligence and internal security agency.
The spies gathered information about Russian military personnel, Defense Department facilities, the regional economy, immigration and social policy. All this was transferred to the Polish side.
Criminal cases were opened under Art. 276 of the Criminal Code of the Russian Federation (espionage). The two detainees were sent to a pre-trial detention center.
Seven other Polish citizens and three Russians who were in contact with the Polish intelligence services were given warnings. Seven Poles were refused entry. In 2026, the visas of another 14 Polish citizens were revoked, and six were banned from entering Russia.
