German federal prosecutors have arrested August Hanning, the former president of the Federal Intelligence Service (BND) from 1998 to 2005, on suspicion of treason, espionage, and attempting high treason. The 80-year-old was detained near Münster and placed in pretrial detention following allegations that he acquired approximately 2,000 classified and highly confidential documents to support his private security consulting business.

Investigators allege that Hanning’s former office manager, Manfred D., provided the intelligence in exchange for payment. The document leak, which spanned from 2010 to 2022, included sensitive information regarding the Iranian nuclear program and Russian military forces. The case is being described as one of the largest intelligence scandals in Europe in recent decades due to Hanning’s high-level access to NATO secrets.

While investigators previously confirmed Russia was not the intelligence service involved, they are investigating Hanning’s alleged contacts with a Chinese military official, Wang Jianzheng, and potential links to Azerbaijani intelligence. Azerbaijan has lodged a diplomatic protest following reports that Hanning may have prepared intelligence analyses for an Azerbaijani officer. British and American intelligence agencies are also investigating whether their own classified information or field agents were compromised.

Reports indicate the investigation surfaced unexpectedly through a legal dispute involving a private matter in Hamburg. Hanning’s legal counsel, Leon Kruse, has denied the allegations, stating his client is being “unjustly prosecuted.” While admitting Hanning possessed confidential documents, the defense maintains that no information was passed for payment or to the detriment of Germany.
