Carsten L. is said to have passed on sensitive information from the Federal Intelligence Service to Russia - and has therefore been in custody for a few days. A media report now suggests that the leak was exposed by a warning from a foreign partner service.
According to a report, the alleged double agent at the Federal Intelligence Service (BND) was exposed by tips from an intelligence service from western countries. Several weeks ago, this intelligence service discovered data "in the Russian apparatus" that could clearly be assigned to the BND, the "Spiegel" reported, citing its own information.
It is said to have been one or more documents dealing with information about Russia. With the warning from the foreign partner service, security experts from the BND were then able to identify the leak in their own ranks, the "Spiegel" reported further.
The suspect Carsten L. was arrested on December 22nd. According to the Federal Prosecutor's Office, he is said to have "transmitted information that he had obtained in the course of his professional activity to a Russian intelligence service".
The "mirror" also reported that in the course of the investigation, another person who works for the BND was targeted by the investigators. In the meantime, however, it is considered unlikely that this person also worked for a Russian secret service. It is more likely that the alleged double agent L. tried to divert suspicion from himself.
