From Kidnapping Case, 2,000 German Intelligence Documents Exposed
An investigation into a child kidnapping case, which initially appeared unrelated to national security, has paved the way towards one of Germany’s most sensitive intelligence matters. During a search of the home of the former head of the German Federal Intelligence Service (BND), August Hanning, investigators discovered traces of approximately 2,000 internal agency documents, which he is alleged to have obtained years after leaving his post.
This discovery served as the gateway to a federal investigation that resulted in the arrest of Hanning and a former high-ranking BND official, Manfred D., on Tuesday (6/10/2026). The German Federal Prosecutor’s Office stated that Hanning is now a suspect in alleged espionage endangering the state, the acquisition of state secrets, attempted treason, and activities as an intelligence agent.
However, this series of cases did not originate from a counterintelligence operation. The starting point was actually a family dispute involving Hamburg entrepreneur Christina Block, which escalated into an investigation into the kidnapping of her two children.
The Block Case Search Becomes a Turning Point
In September 2025, Hamburg investigators searched Hanning’s home and business premises to find evidence related to the Block case. At the time, Hanning was being questioned regarding his alleged involvement in previous attempts to bring Block’s children from Denmark, an accusation the former BND chief has denied.
Christina Block herself is facing legal proceedings regarding the alleged kidnapping of her two youngest children from her former husband’s residence in Denmark during the 2023-2024 New Year period, following a prolonged custody dispute. Block has denied the allegations, and the case is still being processed in the German courts.
As reported by the Associated Press, investigators also suspect that Hanning, along with a former Hamburg criminal police official, previously accepted work related to the attempts to bring the children in 2022 while involved in a security firm. These allegations remain part of the legal process and do not yet constitute a guilty verdict.
While sorting through the items seized during the search, investigators found something far beyond the scope of the Block family matter. According to investigations by WDR, NDR, and Süddeutsche Zeitung featured on Tagesschau, authorities found electronic storage media containing BND documents from a period much more recent than Hanning’s leadership.
Hanning left his position as head of the BND in November 2005. Therefore, the presence of intelligence documents created many years after he no longer led the agency immediately raised questions regarding how the material was obtained.
Approximately 2,000 Documents
The investigation subsequently led to Manfred D., Hanning’s former chief of staff during his tenure at the BND. After working with Hanning at the Ministry of the Interior, Manfred D. returned to the BND and served as chief of staff for several subsequent BND heads from 2012 until March 2026.
This position granted him access to a vast amount of sensitive information. Prosecutors suspect that Hanning and Manfred D. had made an agreement since 2010 to ensure BND information continued to be provided to Hanning in exchange for payment.
According to preliminary findings by the prosecution, Manfred D. allegedly handed over approximately 2,000 documents to Hanning over many years. Many of these documents contained classified information intended solely for the internal use of the BND, including materials used in executive-level intelligence briefings.
Secret information allegedly continued to flow until at least June 2022. This means that if the allegations are proven true, Hanning was still obtaining sensitive material approximately 17 years after no longer leading the BND.
It is important to note that not all 2,000 files can automatically be classified as “state secrets” in the same legal sense. The prosecution stated that many of them contain classified material and information intended for the internal use of the intelligence agency.
