Who Is August Hanning? Ex-German Spy Chief's Alleged Espionage Scheme Uncovered During Heiress Kidnap Probe

August Hanning, the former head of Germany's foreign intelligence service, has been placed in pre-trial detention after prosecutors accused him of obtaining around 2,000 confidential BND documents and using some of the material in work involving foreign intelligence services.

Hanning, 80, led the Federal Intelligence Service, known as the BND, from 1998 to 2005 before serving as a state secretary at Germany's Interior Ministry until 2009. He later worked as a private security consultant.

He was arrested on suspicion of treasonous espionage, attempted treason and other offences involving state secrets. His former BND chief of staff, Manfred D., was also arrested. Both men have been placed in custody.

Who Is August Hanning?

Hanning became BND chief in 1998 and remained in the role until 2005. After leaving the agency, he became a state secretary at the Interior Ministry before moving into private-sector security work.

Federal prosecutors allege that Manfred D. supplied Hanning with approximately 2,000 documents over a period stretching from 2010 to June 2022. Many allegedly contained classified information intended for internal BND use.

Manfred D. continued working for the BND after Hanning's departure, serving as chief of staff to several subsequent agency presidents until his retirement in March 2026. Prosecutors allege that Hanning paid him for the information.

Some of the material reportedly concerned Iran's nuclear programme and the Russian military, while other documents contained intelligence supplied by foreign partner agencies.

Prosecutors allege Hanning used some of the information in his private consulting work. In one case, he is accused of using classified material to prepare an analysis for an officer from a foreign intelligence service. Investigators have not established whether that analysis reached its intended recipient.

Documents Found During Block Investigation

The alleged espionage scheme came to light during a separate investigation involving Hamburg businesswoman Christina Block and the alleged abduction of her children from Denmark in January 2024.

Hanning came under scrutiny in that case, and his property was searched in September 2025. Investigators reportedly found BND documents during the search, prompting federal authorities to examine how the material had reached him. The Federal Prosecutor's Office took over the espionage investigation in May 2026.

Hanning has denied wrongdoing in the Block case. His lawyer has acknowledged that his client possessed confidential documents but denies that he passed information to foreign powers to Germany's detriment or accepted payment for doing so.

Foreign Intelligence Link Remains Unclear

German prosecutors have not identified the foreign intelligence service or services allegedly involved. German media have reported a possible connection to Azerbaijan, including claims that Hanning had contact with an Azerbaijani intelligence operative. Azerbaijan has denied involvement and rejected the reports as unfounded. Reuters also reported that German officials had indicated Russia was not involved.

The case has raised concerns over how sensitive BND material was allegedly removed from the agency and potentially used after Hanning left public service. Current BND chief Martin Jäger said the agency had conducted extensive internal investigations before federal prosecutors took over.

Hanning and Manfred D. remain in custody as the investigation continues. The full extent of the material allegedly obtained and whether classified information reached foreign intelligence services remains unresolved.

If convicted of treason in an especially serious case, German law allows for a life sentence. Other offences alleged in the case carry lower maximum penalties, depending on the charge and circumstances.
