Summary

On 21 December 2022, Carsten L., a senior officer at the German Federal Intelligence Service (BND), was arrested in Berlin on suspicion of betraying state secrets to a Russian intelligence service. The BND's special internal security unit identified Carsten L. as a mole after a foreign partner intelligence agency alerted them months earlier about leaked BND secrets accessible to Russian spies. Carsten L., who works in the highly sensitive Technical Surveillance department responsible for worldwide communications interception, allegedly obtained and passed highly classified BND documents detailing how the service monitors Russia and other intelligence. Although a female colleague was initially suspected of complicity, she was later cleared. The BND and federal prosecutors continue to investigate Carsten L.'s motivation, including potential coercion, with no evidence of financial gain. The case represents a severe breach of Germany's intelligence security and underscores ongoing Russian espionage targeting Western intelligence services.
