Ex-German Spy Chief Arrested on Treason Charges

Germany has arrested former foreign intelligence chief August Hanning, 80, on suspicion of attempted treason and espionage, after prosecutors say a former aide secretly fed him about 2,000 classified documents over more than a decade.

A pipeline of secrets for 16 years

The former president of Germany’s Federal Intelligence Service (BND) was detained on Tuesday, October 6, 2026, the federal prosecutor’s office said, in what is being described as one of the country’s biggest intelligence scandals since the Cold War. Hanning led the BND from December 1998 to November 2005.

Prosecutors say the 80-year-old is “strongly suspected of treasonous espionage, obtaining state secrets, attempted treason and espionage.”

According to the prosecutor’s statement, the arrangement began in the spring of 2010 — five years after Hanning’s tenure ended — when he agreed with a former BND office manager, identified only as Manfred D. under German privacy rules, to receive confidential intelligence information in exchange for payment.

Manfred D. had been Hanning’s chief of staff and went on to serve in the same role for several subsequent BND presidents, from 2012 until March 2026 — a position that gave him access to some of Germany’s most sensitive intelligence, including executive briefings prepared for the chancellery.

Investigators say that over the years Manfred D. supplied Hanning with approximately 2,000 documents, many of them containing classified information meant exclusively for internal use by the intelligence service.

Hanning was arrested in Bad Toelz-Wolfratshausen in southern Germany, while Manfred D. was detained in Steinfurt in western Germany. Both men’s premises were searched, and Manfred D. was charged with aiding and abetting attempted treason and treasonous espionage. Both suspects were to appear before a judge at the Federal Court of Justice.

The consulting link to a foreign service

Prosecutors say Hanning used the classified material in his private consulting work after leaving public office. On one occasion, they allege, he drew on classified intelligence supplied by Manfred D. to draft an analysis for an officer of a foreign intelligence service.

The prosecutor’s office did not identify the foreign service involved, and said it was not immediately clear whether the analysis ever reached its intended recipient. German media outlets including WDR, NDR and the Süddeutsche Zeitung reported that the service in question was not Russian. The magazine Der Spiegel reported that investigators were pursuing a possible connection to Azerbaijan; the federal prosecutor’s office declined to comment on that report.

The chancellery declined to comment on the case.

Why it matters

The arrest of a former head of the BND is unprecedented. A senior security lawmaker warned it could damage Germany’s intelligence relationships with allied nations — a concern given that some of the documents in question reportedly included intelligence shared by foreign partner agencies, as well as sensitive material on subjects such as Iran’s nuclear programme and the Russian military.

The case also raises uncomfortable questions about how an insider pipeline could operate for 16 years without detection, with an aide who served at the heart of Germany’s foreign intelligence apparatus until just months ago.

What’s next

The investigation is expected to widen. Investigators only stumbled onto the case in September 2025, when a search of Hanning’s home during an unrelated matter turned up a storage device containing classified intelligence documents; a broader federal investigation was opened in May 2026.

Prosecutors will now need to establish exactly which documents changed hands, how they were used, and whether any classified material ultimately reached a foreign power. Given Hanning’s age and seniority, the case is likely to become a test of how Germany handles treason allegations at the very top of its former intelligence establishment.
