Germany’s former foreign spy chief has been arrested on suspicion of espionage and treason, prosecutors have said.
August Hanning, 80, is under investigation for attempted treason and acting as an agent for a foreign intelligence service, the Office of the Federal Public Prosecutor General confirmed on Tuesday.
Hanning was president of Germany’s Federal Intelligence Service between 1998 and 2005.
He was arrested in Bad Toelz-Wolfratshausen in southern Germany. His former chief of staff, partially identified as Manfred D, was arrested in Steinfurt in western Germany on suspicion of “aiding and abetting attempted treason and treasonous espionage”.
The prosecutor’s office said, “On one occasion, Hanning used classified intelligence provided by Manfred D to draft an analysis for an officer of a foreign intelligence service.”
Prosecutors said Manfred D also served as the chief of staff for Hanning’s successors between 2012 and 2026, and used his role to gain access to confidential information which he then passed on to Hanning “in exchange for remuneration”. Hanning then used the information in his private consulting work, prosecutors added.
“The current findings suggest that, over the years, Manfred D provided Hanning with approximately 2,000 documents, many of which contained classified information to be used exclusively by the federal intelligence service for internal purposes, particularly for executive intelligence briefings,” the statement said.
The statement did not reveal who the two men were suspected of spying for or which country the foreign agent worked for, adding that “it has yet to be determined if the material reached the intended recipient”.
German MP Marc Henrichmann told the AFP news agency that Germany “will not tolerate the betrayal of secrets”.
Henrichmann, who chairs the German parliament’s intelligence oversight committee, said, “Whoever allies themselves with the enemies of our liberal democracy will be found out.”
The premises of Manfred D and Hanning were being searched in several locations, including in the capital, Berlin.
