German federal police arrested former foreign intelligence chief August Hanning on Tuesday on suspicion of treasonous espionage, obtaining state secrets, attempted treason, and acting as an agent for a foreign service, the Federal Prosecutor’s Office announced.
Officers of the Federal Criminal Police Office took the 80-year-old Hanning and a former aide identified as Manfred D. into custody in the Bad Tölz-Wolfratshausen district of Bavaria and the Steinfurt district of North Rhine-Westphalia. Searches were also underway at premises in Berlin, the prosecutor’s office said in a statement. A judge at the Federal Court of Justice was to review the arrest warrants and decide on pretrial detention.
“The accused Hanning is under strong suspicion of espionage constituting treason,” prosecutors said. They allege that in the spring of 2010, about five years after Hanning left the Federal Intelligence Service, or BND, he and Manfred D. agreed that D. would keep supplying him with valuable intelligence “in exchange for remuneration” for use in Hanning’s private consulting work.
Notably, Hanning was not in the pro-Ukraine political establishment within Germany. In 2024, Remix News reported that Hanning accused Ukrainian President Volodymyr Zelensky of being behind the Nord Stream 2 sabotage attack. Ukrainian suspects have since been arrested and extradited for the attack on critical energy infrastructure.
Manfred D. had been Hanning’s bureau chief and later served as chief of staff to several BND presidents from March 2012 until March 2026, giving him access to sensitive material, the office said. Investigators say that through June 2022 he passed Hanning about 2,000 documents, many classified and intended only for internal BND use, including briefings for the regular intelligence meeting of senior security officials at the Chancellery.
“On one occasion, Hanning used classified intelligence… to draft an analysis for an officer of a foreign intelligence service,” prosecutors said. They added that it was not clear whether “the material reached the intended recipient.”
Hanning is also accused of years of close contact with a representative of a second foreign intelligence service, to whom he passed political information partly drawn from the documents. Prosecutors have not named either service.
Manfred D. is suspected of aiding and abetting attempted treason and treasonous espionage. A government spokesman said the government would not comment because the investigation is ongoing, according to Welt newspaper.
The case grew out of a separate Hamburg investigation. In September 2025, state police searched Hanning’s home and offices for evidence tied to businesswoman Christina Block, who is accused of ordering the kidnapping of her two youngest children in a custody dispute in late 2023. Investigators have alleged Hanning was involved in an earlier kidnapping attempt; he has denied wrongdoing in that case. While reviewing seized material, officers found an electronic storage device holding secret BND documents and referred the find to federal prosecutors in May 2026.
Hanning led the BND from December 1998 to November 2005, then served as a state secretary in the Interior Ministry until 2009. He later worked as an entrepreneur and security consultant. The documents now at issue date from long after he left the service. German media, including WDR, reported that the foreign services involved are not believed to be Russian; prosecutors have not confirmed that account.
