Former German Intelligence Chief August Hanning Arrested on Espionage and Treason Suspicions

BERLIN (Terror Monitor) — German authorities have arrested former Federal Intelligence Service (BND) chief August Hanning on suspicion of espionage, obtaining state secrets and attempted treason in a case that could become one of Germany’s most serious intelligence scandals in decades.

Hanning, 80, was arrested by officers from Germany’s Federal Criminal Police Office (BKA) at his home in Nordwalde, near Münster, on Tuesday morning, according to German media reports and authorities. His former BND office manager, identified under German privacy laws as Manfred D., was also arrested in Bavaria. Properties linked to both men were searched.

Germany’s Federal Public Prosecutor’s Office said Hanning is strongly suspected of treasonous espionage, obtaining state secrets, attempted treason and acting as an agent for a foreign intelligence service. Manfred D. is suspected of aiding and abetting attempted treason and treasonous espionage.

Nearly 2,000 Classified Documents

According to prosecutors and German media reports, the investigation centers on an alleged arrangement between Hanning and his former aide that began around 2010, several years after Hanning left the BND.

Investigators suspect that Manfred D. supplied Hanning with classified intelligence in exchange for payment over a period of years. Prosecutors believe that approximately 2,000 documents were provided, including material intended for internal use within the BND and intelligence briefings prepared for senior officials at the German Chancellery.

German media reports said the documents included highly sensitive intelligence, with some material reportedly concerning the Iranian nuclear program and Russian military activities, as well as information originating from foreign partner intelligence services.

Investigators suspect Hanning used at least some of the classified information in his private consulting activities. In one instance, prosecutors believe he used intelligence supplied by Manfred D. to prepare a security analysis for an officer working for a foreign intelligence service.

Authorities have not identified the foreign intelligence service involved and have not publicly confirmed whether the material actually reached its intended recipient. German media reports citing security sources have said there is no indication that Russia is involved in the case.

Who Is August Hanning?

Hanning served as president of Germany’s Federal Intelligence Service, or Bundesnachrichtendienst (BND), from December 1998 until November 2005.

After leaving the BND, he moved to Germany’s Federal Interior Ministry, where he served as a state secretary until 2009. He later established a private security and consulting business and worked as an adviser in the private sector.

The BND is Germany’s foreign intelligence service and is responsible for gathering intelligence outside the country. The agency has faced several espionage scandals in recent years, making the allegations against a former director particularly sensitive.

How Did Investigators Discover the Alleged Scheme?

According to German authorities and media reports, investigators discovered evidence relating to the alleged transfer of classified BND material while examining a separate case.

German police searched Hanning’s home and offices in September 2025 during an investigation connected to the alleged attempted abduction of the children of German businesswoman Christina Block. During the examination of material seized in that investigation, investigators reportedly discovered classified documents originating from Hanning’s former workplace.

The discovery subsequently led investigators to examine how Hanning had obtained the documents and whether they had been shared with foreign intelligence actors.

Former BND Official Also Arrested

Manfred D., who previously served as Hanning’s office manager, is suspected of having continued to work inside the BND after Hanning left the agency.

Investigators believe he had access to sensitive intelligence and allegedly supplied Hanning with classified information in exchange for money.

German public broadcaster ARD reported that Manfred D. remained employed by the BND until 2026 and allegedly provided Hanning with secret material until at least 2022.

The alleged transfer of information reportedly continued for years, raising questions about how classified intelligence was accessed and removed from one of Germany’s most sensitive government institutions.

Potentially Major Intelligence Scandal

The arrests have triggered concern within Germany over the protection of classified information and the activities of former intelligence officials after leaving government service.

The current BND president, Martin Jäger, said the agency had launched extensive internal investigations after suspicions emerged and emphasized that there could be no compromise on internal security.

The case is particularly significant because some of the allegedly leaked information was reportedly prepared for senior-level intelligence briefings and included material from Germany’s foreign intelligence partners.

The Washington Post described the alleged breach as potentially the most serious to hit the BND since the end of the Cold War, while German media have also raised concerns about the possible impact on trust between Germany and allied intelligence agencies.

Hanning to Appear Before Judge

Hanning and Manfred D. are expected to appear before a judge at Germany’s Federal Court of Justice, which will decide whether they should remain in custody during the investigation.

The investigation remains ongoing, and the allegations have not yet been tested in court. German authorities have not disclosed the identity of the foreign intelligence service allegedly connected to the case or confirmed whether the classified information was ultimately delivered to that service.

The arrests nevertheless represent a major development for Germany’s intelligence community and could lead to further investigations into the handling of classified information within the BND and the activities of former intelligence officials.
