August Hanning, the former head of Germany’s Federal Intelligence Service (Bundesnachrichtendienst, BND), and a senior agency official known as Manfred D have been arrested on suspicion of espionage and attempted treason. The arrests, made in October 2026, stem from allegations that Hanning collected and sold highly classified documents over a period spanning more than a decade after leaving office in 2005.
Hanning, 80, who led the BND from 1998 to 2005, is accused of receiving roughly 2,000 sensitive documents from Manfred D, a former chief of staff at the agency. Investigators believe the documents were shared in exchange for payment beginning in 2010, with Manfred D supplying intelligence up until at least mid-2022. The information reportedly included top-level situation assessments, classified materials from foreign intelligence partners, and details related to Iran’s nuclear program and Russian military operations.
German prosecutors have not publicly identified the recipient of the intelligence briefings allegedly prepared by Hanning, but reports suggest that the foreign intelligence service involved may be linked to Azerbaijan, a close ally of Turkey. It remains unclear if the intelligence ever reached this or other foreign actors. Hanning reportedly used some of the classified information in his private consulting work following his departure from government service.
The investigation began in 2025 during an unrelated police inquiry into Christina Block, a German heiress suspected of orchestrating the abduction of her children. During a search of Hanning’s home, authorities discovered a large cache of sensitive BND documents which he was not authorized to possess. The discovery prompted a federal probe that culminated in the arrests of both Hanning, at his residence near the Dutch border, and Manfred D, at his home in Bavaria.
Manfred D held significant operational influence within the BND, serving as chief of staff to multiple agency presidents between 2012 and 2026. His senior position granted him broad access to classified intelligence, including information received from allied agencies such as those in the United States and the United Kingdom.
The case has raised immediate concerns among Western intelligence agencies about the possible compromise of shared intelligence and exposure of human sources. British and American intelligence services have reportedly initiated internal reviews to assess the extent of any damage and to safeguard the integrity of their information and operatives. Officials emphasize that intelligence sharing protocols typically involve safeguards to limit exposure, but the high level of access possessed by the suspects creates significant risks.
Martin Jäger, the current president of the BND, stated that comprehensive internal investigations were launched promptly upon learning of the suspicions, underscoring a commitment to uncompromising internal security. German lawmakers involved in intelligence oversight condemned the alleged breach, asserting that any betrayal of state secrets will be thoroughly investigated and punished.
Hanning, once regarded as a hawkish voice on Russia and national security, maintained ties with Russian individuals and organisations after leaving the agency. He had made multiple trips to Moscow between 2015 and 2019 and appeared as a witness in support of a prominent Russian businessman in a London trial. He also sat on the board of a Swiss security firm connected to the controversial kidnapping case involving Christina Block.
The investigation is ongoing, with Manfred D having been remanded in custody and Hanning expected to face court proceedings shortly. The case marks one of Europe’s most serious post-Cold War intelligence scandals, underscoring vulnerabilities within established security structures and the complexities of protecting shared intelligence in an interconnected alliance environment.
