A small GPS tracking device was discovered by maintenance workers at PKP Cargo in Poznań, Poland, hidden within a freight car. The device was found during a routine inspection of wagons that had recently travelled through Ukraine and Belarus. Polish police have launched an investigation, overseen by the prosecutor's office, to determine the origin of the device and what data it may have collected. Authorities are currently working to ascertain the purpose of the tracking device and whether it was part of a broader surveillance operation. The discovery raises concerns about potential security breaches and the monitoring of freight transport. The investigation is ongoing, with no immediate conclusions reached regarding the device’s placement or intent. PKP Cargo is cooperating fully with law enforcement officials.
