Germany’s Federal Prosecutor’s Office said on Thursday that it had arrested a US national, identified as Martin D., on suspicion of offering to spy for China.

“The accused is strongly suspected of having declared himself willing to conduct espionage agent activities to a foreign intelligence service,” prosecutors said in a statement.

What are the allegations?

“Until recently, Martin D. worked for the US military services in Germany,” prosecutors said. “In 2024, he contacted Chinese state officials and offered to them to forward sensitive information belonging to the US military to an intelligence service in China.”

Prosecutors said he had acquired the data during his time working with the military. They did not say whether his offer had been accepted or whether he had delivered any information.

The investigations were conducted in close coordination with Germany’s domestic intelligence agency, prosecutors said.

Several recent arrests on espionage allegations

German authorities last month arrested a Chinese woman, who had worked for a logistics services company at the Leipzig/Halle international airport.

She was accused of providing information obtained via her workplace to another Chinese national, Jian G., who is a former employee of the Alternative for Germany (AfD) European Parliament member Maximilian Krah.

Jian G. is accused of forwarding information to China from the European Parliament, with news of this development coming at the height of the European Parliament elections earlier this year, when Krah was the party’s lead candidate.

Three German citizens were also arrested in Düsseldorf and Bad Homburg in April of this year, accused of forwarding on information on military technology.

Several of the other espionage-related investigations in Germany this year pertain to alleged attempts to transfer information to Russia.
