According to a media report, the alleged spy at the Federal Intelligence Service (BND) was also supposed to provide the Russian secret service with information on the positions of artillery and anti-aircraft defenses of the Ukrainian army. As the “Spiegel” reported, it was about the Himars multiple rocket launcher provided by the USA and the Iris-T air defense system supplied by Berlin. The magazine "Focus" meanwhile reported that the alleged spy Carsten L. had betrayed secret BND access to Russian communication systems to Moscow.
According to the investigation, the FSB commissioned Carsten L., through the intermediary Arthur E., to siphon off and hand over GPS data on the position of the Himars rocket launcher and Iris-T to the BND, as reported by “Spiegel”. People familiar with the case told the magazine it was unlikely that such data had been leaked.
According to the report, the alleged order reflects the situation at the front. In the fall, the Ukrainian army had managed to gain spectacular ground – also thanks to the rocket launchers.
Attorney General Peter Frank is investigating L. and E. on suspicion of treason. Both are in custody. E. is said to have handed over secret BND material to the FSB at two meetings in Moscow, which L. had obtained from his employer.
The Russian side may have paid royally for the alleged espionage, the “Spiegel” reported. Investigators found a six-digit sum of cash in envelopes in Carsten L.'s locker. E. is said to have received these envelopes from the FSB and handed them over to L.
Representatives of the BND assumed that the FSB wanted to retain L. in the long term. According to "Spiegel", L.'s defense attorney Marvin Schroth did not want to comment on request, so E.'s lawyer left a request unanswered. The Federal Prosecutor's Office and the BND also refused to react.
Meanwhile, "Focus" reported, citing investigators, that important information had apparently been passed on. According to this, Carsten L., with the help of his courier Arthur E., is said to have delivered around 100 top-secret dossiers on BND techniques for penetrating the communication channels of Russian government agencies and secret services. Carsten L. was last head of department for BND radio espionage.
