Germany Arrests Former BND Chief August Hanning on Treason and Espionage Charges

August Hanning, 80, led Germany's Federal Intelligence Service, the BND, from December 1998 to November 2005. On Tuesday, October 6, 2026, Germany's Federal Prosecutor's Office said he was arrested and is "strongly suspected of treasonous espionage, spying out state secrets, attempted treason, and espionage," according to Associated Press reporting carried by CNN.

A second man, identified only as Manfred D., was arrested the same day. Prosecutors charged him with aiding and abetting attempted treason and treasonous espionage.

Where the arrests happened is actually in dispute

The reporting conflicts on location details. The Associated Press, via CNN, says Hanning was arrested in Bad Tölz-Wolfratshausen in southern Germany, and that Manfred D. was picked up separately in Steinfurt, in western Germany. The Spanish outlet ARA and a Sky News dispatch carried by V2 Radio back that version, both saying Hanning was taken into custody in Bad Tölz-Wolfratshausen.

But the BBC, Defence24, and Anadolu Agency, the latter citing German public broadcasters WDR and NDR along with Süddeutsche Zeitung, say the opposite: that Hanning was arrested at his home in Nordwalde near Münster (which sits in the Steinfurt district), while Manfred D. was arrested in Bavaria. Neither cluster of outlets has corrected the other as of this writing, and the Federal Prosecutor's Office statement itself, as quoted across sources, does not specify locations. The two men's whereabouts were searched, but which suspect was picked up where remains unresolved.

The alleged scheme

What is not in dispute is the core allegation. Manfred D. served as Hanning's chief of staff during his BND tenure and went on to hold the same post for subsequent BND presidents from March 2012 until March 2026, according to the Federal Prosecutor's Office statement reported by CNN and the BBC.

Prosecutors say the two men agreed in spring 2010 that Manfred D. would continuously pass BND intelligence to Hanning "in exchange for remuneration." Over the years that followed, prosecutors allege, Manfred D. supplied Hanning with roughly 2,000 documents, many classified for internal BND use only, including material prepared for the Chancellery's weekly executive intelligence briefings.

Bild newspaper reported that Hanning used the material, and intended to resell it, as part of his private security consulting business, according to accounts from Daily Sabah and Anadolu Agency. Prosecutors say that on at least one occasion, Hanning used classified intelligence to draft an analysis for an officer of a foreign intelligence service, though they say it hasn't been determined whether the material actually reached its intended recipient.

Which country? Still unknown

Prosecutors have not named the foreign power or powers involved, and that is the biggest open question in this case. Germany's Welt newspaper reported that suspicions have circulated for years that Hanning cooperated with Russia's FSB security service, according to ARA. But an investigation by WDR, NDR, and Süddeutsche Zeitung, also cited by ARA, concluded that Russia's services are not among the foreign agencies Hanning is suspected of working with, even though the leaked files reportedly included material on the Russian army and Iran's nuclear program.

Neither claim has been confirmed by prosecutors. Nobody outside the investigation knows for certain, and Germans deserve a straight answer before this gets spun into a geopolitical football.

How it surfaced

According to multiple outlets, the case emerged out of an unrelated investigation into German businesswoman Christina Block, who Hamburg prosecutors accuse of orchestrating the 2023 kidnapping of her two children amid a custody dispute. The BBC reports investigators allege Hanning was involved in an earlier, failed kidnapping attempt, which Hanning denies. State police reportedly found an electronic storage device containing recent BND documents during that separate probe, which is what triggered scrutiny of Hanning's post-government consulting work.

Prior cases

The BND has faced treason allegations before. The BBC notes a BND officer identified as Carsten L. was charged with treason in 2023 for allegedly passing intelligence on the Ukraine war and the Wagner mercenary group to Russia, reportedly receiving around €400,000.

Sueddeutsche Zeitung, as cited by Daily Sabah and Anadolu Agency, described the Hanning case as potentially one of the largest espionage affairs in the history of the Federal Republic of Germany. Manfred D. is scheduled to appear in court Tuesday. Hanning is due in court Wednesday, October 7, 2026, according to the BBC. Whether prosecutors will name the foreign power involved before then, or whether that detail stays sealed through the proceedings, is still an open question.
