Former head of German intelligence BND detained in espionage investigation
Former head of German foreign intelligence August Hanning was detained on Tuesday. The Federal Prosecutor's Office is investigating suspicions of obtaining state secrets and espionage activities.
Detention of former BND head
According to the Journal of Legal Affairs, former head of German foreign intelligence August Hanning was detained on 6 October at his home in Nordwalde in North Rhine-Westphalia. The operation was carried out by officers of the Federal Criminal Police Office. At the same time, a former high-ranking BND employee who served as head of Hanning's office was detained in Bavaria.
The Federal Prosecutor's Office is conducting proceedings concerning suspicions related to obtaining state secrets, attempted treason and agent activity on behalf of a foreign intelligence service. In the case of the second detainee, investigators are examining suspicions of complicity. At the present stage, these are charges formulated within the proceedings, and the case has not been decided by a court.
Decades of access to classified documents
Hanning headed the Federal Intelligence Service BND from 1998–2005. After leaving his position, he served as state secretary in the federal Ministry of the Interior, and subsequently worked as an entrepreneur and security adviser.
Investigators suspect that long after leaving the BND, Hanning obtained highly classified materials originating from the service. According to findings by WDR, NDR and "Süddeutsche Zeitung", a former colleague of Hanning allegedly passed him classified information over many years, and received money for the documents transmitted. The practice allegedly continued at least until 2022.
Two thousand documents
Investigators assumed that approximately two thousand documents could have reached Hanning in this way. Among the materials were documents prepared for periodic briefings on the intelligence situation at the Chancellor's Office — meetings during which representatives of Germany's most important security institutions exchange particularly sensitive information.
The documents concerned, among other things, Iran's nuclear programme and Russian armed forces. Some of the information came from foreign services cooperating with Germany. Potential disclosure of such data could have been significant both for German security and for the BND's relations with partner intelligence agencies.
Preparation of analyses for a foreign intelligence service
One of the most serious lines of the investigation concerns the use of the information obtained. According to findings by German media, Hanning allegedly prepared at least one security analysis based on classified materials for a foreign intelligence service. In another case, he allegedly used information from internal BND documents during contacts with a foreign agent.
German media indicate that in the case of the service for which the analysis was to be prepared, it was not Russia. It has not been disclosed which country is in question. The prosecutor's office is investigating both the manner in which documents left the BND and who could have later gained access to the information contained in them.
Discovery during a search
Hanning came under the attention of investigators following a search of his home in September 2025. Officers were conducting activities in connection with a case involving entrepreneur Christina Block concerning a custody dispute.
During the analysis of the secured materials, officers came across an electronic storage device containing a large number of BND documents. The problem was that Hanning had not worked in the service since 2005, whilst some of the documents found came from a much later period. The materials were passed to the federal authorities, and in May 2026 the Federal Prosecutor's Office initiated proceedings.
Questions about the security system
A key question remains how such a large number of confidential materials could have left the structures of German intelligence. The former BND employee detained together with Hanning was alleged to have remained in the service until spring 2026.
Investigators are examining the period in which documents were passed to the former BND head, and the mechanism by which they were removed or copied. If the findings are confirmed, it would mean that confidential information reached a person outside the service for several years.
Particularly significant is the fact that some of the documents contained information obtained by Germany from foreign partners. In the special services community, protection of such data is of fundamental importance for further cooperation and exchange of information between allies.
