Germany’s former spy chief has been arrested in a federal treason and espionage investigation after investigators found highly classified BND material in his home, including files dated years after he left the service.
The Arrest and the Charges
August Hanning, BND president from 1998 to 2005 and later state secretary in the Interior Ministry, was pulled out of his house in Nordwalde near Muenster by federal criminal police. The Federal Public Prosecutor’s Office is pursuing him for suspected treasonous espionage, obtaining state secrets, attempted treason, and intelligence-agent activity, and has placed him under arrest.
A second former senior BND employee, Manfred D., was arrested in Bavaria. Investigators say he fed Hanning highly classified BND material for money until at least 2022. Around 2,000 classified documents are believed to have moved between them.
What Was in the Files
Many of the documents were briefings prepared for the ND Lage at the Federal Chancellery, the room where the heads of Germany’s security agencies exchange intelligence. The contents included extremely sensitive assessments of Iran’s nuclear programme, assessments of Russia’s armed forces, and intelligence originating from foreign partner services.
Investigators suspect Hanning used at least some of it to prepare a security analysis for a foreign intelligence service, and in that specific case the service was not Russia. In another case he is alleged to have used classified BND material in communications with a foreign agent.
If a former BND president sat on a cache of allied-supplied material, every partner service now has to ask how long that material was circulating and who else saw it.
How the Trail Started
The investigation began somewhere unexpected. Hamburg investigators searched Hanning’s home and offices in September 2025 during a separate investigation connected to the Christina Block kidnapping case. They found an electronic storage device containing highly classified BND material he had no business holding. Some of it dated as recently as June 2022, years after he left the service.
Hamburg LKA handed the device to federal authorities, and the Federal Public Prosecutor’s Office opened the classified investigation in May 2026.
The Real Damage
For Germany’s intelligence community the real damage is trust. Every partner service now has to ask how long allied-supplied material was circulating and who else saw it.
The allegations remain unproven in court, but the sequence is already a security failure with a two-thousand-document paper trail.
