Germany’s Federal Prosecutor General had August Hanning arrested on 6 October 2026 on suspicion of treasonous espionage and attempted treason. Prosecutors allege his former office manager passed him about 2,000 BND documents between 2010 and June 2022 in exchange for payment. No indictment has been filed.
Hanning, 80, led the Bundesnachrichtendienst, Germany’s foreign intelligence service, from December 1998 until the end of November 2005. The case is a German criminal investigation, announced by the Generalbundesanwalt, the Federal Prosecutor General, in Karlsruhe. Everything set out below is an allegation by prosecutors at the investigation stage. Neither man has been tried or convicted, and both are presumed innocent.
What Prosecutors Allege Happened
The allegation is a commercial one rather than an ideological one: that a former intelligence chief paid a serving official for secret material. According to the Federal Prosecutor General’s account, Hanning, 80, and his former office manager agreed in spring 2010 that the official would obtain valuable BND findings for Hanning in return for payment.
Prosecutors say that roughly 2,000 documents were passed to Hanning up to June 2022. Many were classified and marked for internal use within the BND only, and reporting on the case indicates the material included briefings prepared for the German chancellery. The BND, or Bundesnachrichtendienst, is Germany’s foreign intelligence service, equivalent in role to Britain’s MI6.
Prosecutors further allege that Hanning maintained close contact over many years with a member of another state’s intelligence service and supplied that person with political information, some of it drawn from BND material. German reporting indicates that at least one written analysis was prepared for a foreign intelligence contact, and that it has not been established whether it was delivered.
The Four Offences Under Investigation
German law divides this territory into separate offences, and prosecutors have named four in Hanning’s case. The German terms matter because they are not interchangeable with English-language labels such as “treason”.
- Landesverräterische Ausspähung: treasonous espionage, meaning the gathering of state secrets with the intention of passing them to a foreign power.
- Auskundschaften von Staatsgeheimnissen: obtaining or scouting out state secrets.
- Versuchter Landesverrat: attempted treason. The word “attempted” is doing work here: it indicates prosecutors do not allege a completed act.
- Geheimdienstliche Agententätigkeit: acting as an agent for a foreign intelligence service.
Arrest warrants for both men were issued by the investigating judge at the Federal Court of Justice, the Bundesgerichtshof. In German procedure, a warrant at that stage requires strong suspicion, a threshold short of the proof required for conviction, and it is not a finding of guilt.
The Second Man Arrested
A second arrest was made the same morning, and his position inside the service is central to the allegation. The man, identified in German reports only as Manfred D. in line with German privacy practice, is suspected of aiding and abetting attempted treason and treasonous espionage.
He was Hanning’s office manager and went on to serve as office manager to several subsequent BND presidents, from March 2012 until March 2026. That span is the reason the case is being treated seriously in Berlin: the alleged access continued for years after Hanning himself had left, and reached the office of a sitting intelligence chief.
The two men were arrested in different parts of the country. Hanning was detained in the district of Steinfurt in North Rhine-Westphalia and Manfred D. in the Bavarian district of Bad Tölz-Wolfratshausen.
Why No Country Has Been Named
Prosecutors have not identified the foreign intelligence service, and that omission is the largest gap in what is publicly known. The announcement refers to a member of another state’s intelligence service without naming the state.
Süddeutsche Zeitung reported that the case does not involve Russia. That has not been confirmed by prosecutors, and no other country has been confirmed or ruled out on the record. Readers should treat any named country circulating in commentary as unverified: on the official account, the recipient’s identity is simply not public.
The scale of any resulting harm is also unestablished. Luca Manns of the intelligence research unit at the University of Cologne said it is not yet possible to say in how many other instances findings may have flowed out verbally or in writing. That is an assessment of uncertainty, not a measurement of damage.
How the Case Surfaced
The investigation did not begin as an espionage inquiry. According to the Federal Prosecutor General, it grew out of material found during a search of Hanning’s home carried out by the Hamburg State Prosecutor’s Office in September 2025, in a separate investigation concerning Christina Block and others.
That separate Hamburg matter is unconnected to the espionage allegations, and German media have reported that Hanning denies wrongdoing in it. The espionage findings were referred to the Federal Prosecutor’s Office for it to take over in early May 2026, five months before the arrests. Germany has not been alone in revisiting how espionage is prosecuted, with other countries also tightening the law in recent years.
What Happens Next
The immediate steps are procedural, and none of them determines guilt.
- Appearance before the investigating judge: both men were due to be brought before the investigating judge at the Federal Court of Justice, who decides whether each remains in custody.
- Continuing investigation: the Federal Prosecutor General’s inquiry remains open. No charge sheet has been filed.
- A possible indictment: if prosecutors decide to charge, an indictment would go to a higher regional court, which would then decide whether to open a trial. No date exists for any of this.
Hanning did not respond to a request for comment, according to reporting on 6 and 7 October 2026, and the German chancellery declined to comment. As of 7 October 2026, no statement from the BND or from the parliamentary oversight committee had been reported, and neither man had publicly answered the espionage allegations.
What Is Established, Alleged and Unknown
With a case at this stage, the three categories are worth keeping apart.
- Established: two men were arrested on 6 October 2026; arrest warrants were issued by the investigating judge at the Federal Court of Justice; the Federal Prosecutor General announced the suspicions and their general substance.
- Alleged by prosecutors, and untested: the 2010 agreement, the payments, the roughly 2,000 documents up to June 2022, and the years of contact with a foreign intelligence officer.
- Unknown or unconfirmed: which foreign service and which country; whether any analysis was actually delivered; what, if anything, was compromised; and whether charges will follow at all.
