Former German spy chief Hanning detained over 2,000 secret documents

Former German foreign intelligence chief August Hanning was detained on 6 October 2026 on suspicion of treasonous espionage, obtaining state secrets, attempted treason and espionage, the federal prosecutor's office said. Hanning, 80, who led the BND from December 1998 to November 2005, allegedly paid for secret documents and used them to prepare an analysis for a foreign intelligence service.abc.net.au+1

The detention of a former head of Germany's foreign intelligence service is unprecedented and could damage the country's intelligence relationships with allied nations, according to a senior security lawmaker. The prosecutor's office did not identify the foreign intelligence service, and it was not immediately clear whether the analysis reached its intended recipient.

What prosecutors allege

Prosecutors said Hanning is strongly suspected of treasonous espionage, obtaining state secrets, attempted treason and espionage. Five years after his seven-year tenure as BND head ended in 2005, Hanning agreed with a former BND office manager, identified as Manfred D., to receive confidential intelligence information in exchange for payment, according to prosecutors.tbsnews.net

Hanning was arrested early on 6 October at his home in Nordwalde near the western German city of Münster, according to information from WDR, NDR and the Süddeutsche Zeitung. Manfred D. was taken into custody in Bavaria. Authorities searched both suspects' properties as well as locations in Berlin, the prosecutor said.

Manfred D. served as office manager to successive BND presidents until March 2026, giving him access to current intelligence while prosecutors say documents were being siphoned. From 2012 to March 2026 he was chief of staff to Hanning's successors. Prosecutors say he supplied about 2,000 documents over the years, including material classified for internal BND use only.

How the documents moved

The documents included senior-level intelligence briefings at the chancellery, the Süddeutsche Zeitung reported. Prosecutors say Hanning used the classified information to prepare an analysis for an officer of a foreign intelligence service and, for years, shared political information with a representative of that agency. D. is alleged to have provided Hanning information until at least mid-2022.

Prosecutors said the arrangement was reached in 2010, and Hanning used the information in his private consulting work. Ines Peterson, a spokesperson for the federal prosecutor's office, told German broadcaster RTL that in one instance Hanning used classified information to prepare an analysis for an employee of a foreign intelligence service.

The Spiegel news magazine reported investigators were pursuing a possible connection to Azerbaijan, saying Hanning had been in contact with an agent from that country. The federal prosecutor's office declined to comment on that report. The Süddeutsche Zeitung reported the case does not involve Russia. Hanning did not respond to a request for comment; the chancellery declined to comment.

Political reaction and next steps

BND President Martin Jaeger said the agency launched extensive internal investigations as soon as suspicions emerged, adding: "There can be no compromises on internal security." Marc Henrichmann, who chairs the German parliament's intelligence oversight committee, said Germany "will not tolerate the betrayal of secrets." Opposition lawmaker Konstantin von Notz called the allegations "deeply troubling."

Roderich Kiesewetter, a conservative security expert, told the Handelsblatt newspaper that cases of this kind were "particularly burdensome for trust and particularly damaging for Germany." DW's chief political editor Michaela Küfner described the case as Germany's "biggest espionage scandal of the century." The investigation reportedly began through Hanning's connection to a trial involving businesswoman Christine Block.

Both suspects were due to appear before an investigating judge at the Federal Court of Justice on Tuesday and Wednesday. Hanning served as interior ministry state secretary until November 2009. The case ranks among Germany's biggest intelligence scandals since the Cold War, following the 1974 Brandt aide affair and the 1990 exposure of Klaus Kuron as a Stasi spy.
