The August Hanning espionage case is a criminal investigation in Germany concerning allegations that August Hanning, former president of the Federal Intelligence Service (Bundesnachrichtendienst, or BND), obtained confidential agency documents after leaving office and used classified information in dealings with foreign intelligence personnel. Hanning and a former aide, publicly identified as Manfred D., were arrested on 6 October 2026. The allegations remained contested: Hanning’s lawyer denied that his client had passed information to Germany’s detriment or in exchange for payment. (presseportal.de)
Background and discovery
Hanning headed the BND from 1998 to 2005. He subsequently served as a state secretary in the Federal Ministry of the Interior before entering private-sector security consulting. Manfred D. was a former aide who continued working within the BND after Hanning’s departure, serving as chief of staff to several subsequent agency presidents between March 2012 and March 2026.

The espionage investigation originated in evidence discovered during a September 2025 search of Hanning’s premises in a separate investigation involving Christina Block and others. The matter was referred to the Federal Prosecutor General in early May 2026. Reporting by NDR, WDR and Süddeutsche Zeitung described the discovery of an electronic storage device containing sensitive BND material. (presseportal.de)
Allegations
According to prosecutors’ account, Hanning and Manfred D. allegedly reached an arrangement around 2010 under which D. would supply valuable BND information in return for payment. Investigators alleged that approximately 2,000 documents were supplied through June 2022 and that Hanning used the information for financial advantage in his consulting activities. These were allegations concerning conduct after his presidency of the service, rather than during his tenure as BND chief. (zdfheute.de)
Prosecutors alleged that, in one instance, Hanning used classified information to prepare an analysis intended for an employee of a foreign intelligence or security apparatus. They expressly stated that investigators had not established whether the analysis reached its intended recipient. The authorities did not publicly identify the country concerned. (zdfheute.de)
The suspected offenses cited in the arrest announcement were treasonous espionage, obtaining state secrets, attempted treason and intelligence-agent activity, under sections 96, 94 and 99 of the German Criminal Code. Manfred D. was suspected of aiding and abetting attempted treason and treasonous espionage. These descriptions identify the legal grounds of the investigation, not findings of guilt.

Arrests, detention and defense response
Federal Criminal Police Office officers arrested both suspects on 6 October 2026 pursuant to warrants issued by an investigating judge at the Federal Court of Justice. Searches were also conducted at premises associated with the suspects, including in Berlin. Manfred D. entered pretrial detention that day; an investigating judge ordered Hanning’s pretrial detention on 7 October. (presseportal.de)
Hanning’s lawyer, Leon Kruse, acknowledged that his client possessed confidential documents but rejected the allegation that he had passed their contents on to Germany’s detriment, particularly for payment. The defense response therefore distinguished possession of documents from the alleged disclosure and commercial exploitation of their contents. (apnews.com)
Parliamentary oversight
The case also prompted scrutiny of intelligence-service security and former officials’ private employment. In a public assessment reported on 8 October 2026, the Bundestag’s Parliamentary Oversight Panel stated that it had received a comprehensive government briefing and commissioned an ad hoc inspection by its permanent authorized representative. The inspection was intended to clarify the circumstances and help address structural or organizational problems. (bundestag.de)
The panel also reiterated concerns first expressed in May 2023 about former public officials undertaking private work closely related to their previous security or intelligence responsibilities without adequate scrutiny. It identified potential conflicts of interest and risks arising from the transfer of professionally acquired knowledge and capabilities to foreign state or private organizations. (bundestag.de)
