Germany's Former Spy Chief August Hanning Arrested on Suspicion of Treason and Espionage

German authorities have arrested August Hanning, the former president of the country's Federal Intelligence Service, on suspicion of treason and espionage, prosecutors confirmed on Tuesday.

Hanning, 80, led the Bundesnachrichtendienst (BND), Germany's foreign intelligence agency, from 1998 to 2005. He was taken into custody in Bad Toelz-Wolfratshausen, a town in the southern state of Bavaria, according to the Office of the Federal Public Prosecutor General.

The arrest marks a stunning development in a country where intelligence officials are entrusted with protecting some of the nation's most sensitive secrets. Hanning spent seven years at the helm of the BND before leaving the agency and later establishing himself as a private security consultant.

Prosecutors say Hanning is under investigation for attempted treason and for acting as an agent on behalf of a foreign intelligence service.

A second suspect, identified only as Manfred D, was arrested in Steinfurt, located in western Germany. Manfred D previously served as Hanning's chief of staff and, according to prosecutors, went on to hold the same position under Hanning's successors between 2012 and 2026, giving him sustained access to highly classified material over many years.

The prosecutor's office alleged that Hanning used classified intelligence supplied by Manfred D to prepare an analysis for an officer of a foreign intelligence service. This single documented instance forms part of a broader pattern that investigators are now piecing together.

According to the federal prosecutors, Manfred D exploited his position to obtain confidential information and then passed it to Hanning in exchange for payment. Hanning is suspected of then using that material in his private consulting business, effectively turning state secrets into a commercial asset.

The scale of the alleged leak is significant. Prosecutors said their current findings indicate that over the years Manfred D handed Hanning roughly 2,000 documents. Many of these contained classified information intended exclusively for internal use by the federal intelligence service, including material prepared for executive intelligence briefings.

Officials have not disclosed which country the two men are suspected of spying for, nor have they identified the foreign intelligence service that allegedly received or was meant to receive the material. The prosecutor's statement noted that it has yet to be determined whether the documents ultimately reached their intended recipient.

German police searched properties linked to both men in multiple locations, including in Berlin, the capital. The searches suggest investigators are still gathering evidence and attempting to establish the full scope of the suspected operation.

Marc Henrichmann, a member of the German parliament who chairs its intelligence oversight committee, responded to the arrests by saying Germany "will not tolerate the betrayal of secrets." He added that "whoever allies themselves with the enemies of our liberal democracy will be found out."

Henrichmann's comments reflect the political sensitivity of the case. Germany's intelligence oversight committee is tasked with scrutinizing the work of the BND and other agencies, and any breach involving a former agency head raises uncomfortable questions about internal controls and vetting procedures.

Hanning's tenure at the BND coincided with a period of major transformation for German intelligence. He led the agency through the aftermath of the September 11 attacks, when Western intelligence services dramatically expanded their counterterrorism operations, and he was later called to testify before a parliamentary committee investigating the National Security Agency spying scandal.

The case also raises questions about the revolving door between government intelligence work and private consulting. Hanning's transition from running the BND to advising private clients put him in a position where his knowledge and contacts were commercially valuable, and prosecutors now allege that some of that value was derived from material he should never have possessed outside government channels.

For Manfred D, the allegations suggest a long-running scheme conducted from inside the intelligence apparatus itself. If the prosecutors' account holds, he spent more than a decade in proximity to sensitive information while allegedly funneling documents to a former boss, an arrangement that would represent a serious failure of internal security.

Neither the BND nor the German interior ministry has issued a detailed public response to the arrests. The investigation remains active, and further charges could follow as prosecutors review the documents seized during the searches.

The outcome of the case will likely shape the debate in Berlin over how Germany safeguards classified information and how it monitors officials who leave sensitive positions. The fact that the primary suspect is a former spy chief, and the alleged accomplice a long-serving chief of staff, makes the affair especially damaging to the reputation of the service both men once served.
