German authorities have arrested an American citizen, identified as Martin D., on suspicion of espionage for allegedly offering sensitive U.S. military information to Chinese intelligence. Martin D., a former employee of the U.S. Armed Forces in Germany, reportedly contacted Chinese officials in 2024, proposing to transmit classified data. The arrest took place in Frankfurt, with the German federal prosecutor's office and domestic intelligence service collaborating on the investigation. Although the suspect was prepared to engage in espionage activities, reports suggest he had not yet transferred any information before his arrest. This incident highlights ongoing concerns about foreign espionage activities in Germany, following other similar cases involving both American and German nationals allegedly spying for China. Further details are expected as investigations continue.
