Germany Arrests Its Former Spy Chief on Suspicion of Espionage and Treason

August Hanning, the former president of Germany's Federal Intelligence Service, was arrested Tuesday morning on suspicion of espionage and treason, the federal prosecutor's office in Karlsruhe confirmed. A second man, a former senior BND employee identified only as Manfred D., was arrested the same day. Both are suspected in a years-long arrangement prosecutors say involved classified intelligence documents and payments.

The Arrest That Shook Berlin

Federal Criminal Police Office investigators arrested August Hanning, the former president of Germany's Federal Intelligence Service, on Tuesday morning, 6 October 2026, on suspicion of espionage and treason. The federal prosecutor's office in Karlsruhe confirmed the arrest. Hanning is 80 years old and led the BND from December 1998 to November 2005. He later served as state secretary at the Federal Ministry of the Interior until November 2009, a non-party appointee under then CDU interior minister Wolfgang Schäuble. After leaving government he moved into the private sector, working as a security and business consultant and running his own security firm. A second man, a former senior BND employee identified only as Manfred D. because of German privacy rules, was arrested the same day. Searches were carried out Tuesday at both suspects' premises and in Berlin. Hanning is due to appear before an investigating judge on Wednesday.

What Prosecutors Allege

The federal prosecutor's office says Hanning is "strongly suspected of treasonous espionage, spying out state secrets, attempted treason, and espionage." Prosecutors allege the two suspects agreed, probably in spring 2010, that the former aide would continuously procure valuable BND intelligence for Hanning in exchange for payment. The aide is alleged to have supplied Hanning with approximately 2,000 documents over the years. Many contained classified information intended exclusively for the BND's internal purposes, particularly for executive intelligence briefings. Manfred D. provided the material until at least mid 2022, though the federal prosecutor's charges cover only the period up to June 2022. Hanning allegedly paid for the information with the aim of using it profitably in his private consultancy work. In one instance, prosecutors say, Hanning used intelligence obtained from Manfred D. to draft an analysis for an officer of a foreign intelligence service. The federal prosecutor said it has yet to be determined whether the material reached the intended recipient.

The Aide at the Centre

The co-suspect is identified only as Manfred D. because of German privacy rules. He served as Hanning's chief of staff at the BND and followed Hanning to the Federal Interior Ministry as a seconded assistant between December 2005 and November 2009. From March 2012 to March 2026 he was chief of staff to several of Hanning's successors as BND president, giving him sustained access to highly confidential information. He remained at the BND leadership level until his retirement in March 2026. He faces charges of aiding and abetting attempted treason and treasonous espionage. He is due to appear before the Federal Court of Justice in Karlsruhe. Hanning is due to appear before an investigating judge on Wednesday, 7 October.

The Foreign Intelligence Question

The prosecutor's office did not say which foreign intelligence service was involved, and said it has yet to be determined whether the material reached the intended recipient. Prosecutors say Hanning was also in close contact with a representative of another foreign intelligence service, to whom he passed on political information, partly based on material provided by Manfred D., over several years. WDR, NDR and the Süddeutsche Zeitung report the case does not concern a connection to Russia. Berliner Morgenpost reported, from its own information, that the foreign service is not Russia. Der Spiegel reported that the political information Hanning supplied to the member of the other state intelligence service probably did not count as classified. The documents reportedly included intelligence reports meant for the Chancellery. No foreign government has been named by prosecutors, and no determination has been made public about whether any material reached a foreign power.

How the Case Surfaced

The investigation did not begin with counter-intelligence. It began with a search at Hanning's home in September 2025, carried out by Hamburg state criminal police officers in connection with the case of Christina Block. Block is a German steakhouse-chain heiress. Hamburg prosecutors accused her of orchestrating the kidnapping of her two youngest children in 2023 amid a custody dispute. The children were living with their father in Denmark and were taken from the father and brought to Germany, to their mother, by staff of an Israeli security firm, according to ORF.at. Prosecutors said Hanning and a retired LKA Hamburg officer were suspected of accepting a commission from Block of more than 100,000 euros, about $112,000, in 2022 to return the children from Denmark. Hanning denies involvement in an attempted kidnapping of the children. During searches of his private and office premises, investigators found the BND material.

The Documents That Mattered

State criminal police officers reportedly discovered an electronic data storage device containing sensitive information, including recent BND documents, during the September 2025 searches. The material belonged to the "Nachrichtendienst-Lage," the regular meeting of senior security-agency officials at the Chancellery, also known as the chancellery intelligence briefing. Many of the documents were classified as Verschlusssache, the German category for restricted material. What sets the case apart from a conventional leak is where the paper came from: on the prosecutor's account, the documents were pulled from the service's own internal reporting, particularly material prepared for executive intelligence briefings, and handed over in exchange for money. The case passed to the federal prosecutor in May 2026, months after the September 2025 search first put the documents in investigators' hands.

Inside the BND's Response

Current BND president Martin Jäger, a trained diplomat who took office in September 2025, said the service had launched "early and immediately extensive internal investigations" which hardened the suspicion against Hanning. "Für den BND und mich gibt es bei der internen Sicherheit keine Kompromisse," Jäger said, meaning: "For the BND and for me there are no compromises on internal security." He added: "Keines meiner Ziele, keine meiner Prioritäten werden durch diesen Vorgang in Frage gestellt," meaning: "None of my goals, none of my priorities are called into question by this matter." DW's chief political editor Michaela Küfner, reporting from a government press briefing, called the case Germany's "biggest espionage scandal of the century unfolding in real time." ZDF correspondent Klaus Brodbeck said: "Es ist ein großer Skandal für den BND," meaning "It is a major scandal for the BND," and, if the suspicion is confirmed, "eine Katastrophe," a catastrophe.

The Political Fallout

The arrest lands while legislation to strengthen the intelligence services' powers is mid-way through the parliamentary process. The bill would upgrade the BND from a pure information-collecting service into an operationally capable one: authorising "hackbacks," actively disrupting or disabling hostile foreign IT infrastructure, permitting the disruption or manipulation of drone systems abroad, and strengthening the BND's powers of data analysis. Konstantin von Notz, the Greens' security spokesman, told Berliner Morgenpost: "Wir erwarten sofortige Aufklärung der ungeheuren Vorwürfe," meaning "We expect immediate clarification of these monstrous allegations." He added: "Auch der gegebenenfalls entstandene nachrichtendienstliche Schaden muss ebenso umgehend wie umfassend ab- und aufgeklärt werden," meaning any intelligence damage that may have occurred must also be resolved and clarified as immediately as it is comprehensively. He called the developments "ein Einfallstor für gegnerische Geheimdienste," a gateway for hostile intelligence services. Marc Henrichmann, the CDU politician who chairs the parliamentary control committee for the intelligence services, said handling of secret information is "eine Frage der nationalen Sicherheit" — a question of national security — and not a trivial matter, and said Hanning had betrayed "die Werte der deutschen Sicherheitsbehörden," the values of the German security agencies. Bild's headline framing: "Der Verdacht ist Landesverrat," the suspicion is treason.

Two Accounts of the Arrests

The two accounts assign the same two places to the two men in opposite order. The Associated Press, via NPR, CBC and the New York Post, reported Hanning was arrested in Bad Tölz-Wolfratshausen in southern Germany and that Manfred D. was arrested in Steinfurt in western Germany. Deutsche Welle, i24NEWS, TVP World, Berliner Morgenpost and the German outlets WDR, NDR and Süddeutsche Zeitung report the reverse: Hanning was arrested at his home in Nordwalde near Münster, which is in Steinfurt district in western Germany, and Manfred D. was taken into custody in Bad Tölz-Wolfratshausen, in Bavaria. The discrepancy has not been resolved by officials. Prosecutors have confirmed only that two men were arrested on Tuesday and that searches were carried out at both suspects' premises and in Berlin. Both suspects are presumed innocent. No charging document specifying locations has been made public.

What Happens Next

Hanning is due to appear before an investigating judge on Wednesday, 7 October; Manfred D. is due before the Federal Court of Justice in Karlsruhe. Prosecutors have not said when either man might be charged. Two questions will shape what follows. The first is whether the analysis written for a foreign intelligence officer to read ever reached its intended recipient, which the federal prosecutor says remains undetermined. The second is what the case does to the intelligence-reform bill now before parliament, with its provisions on hackbacks, drone-system disruption and expanded data analysis still under consideration. Bild reported that Hanning faced financial difficulties linked to a position on the supervisory board of a Baltic bank that was allegedly embezzled and later went bankrupt — a claim attributed to Bild.
