PARIS — Prosecutors in Paris opened an investigation Wednesday into allegations that Chinese citizens had sought to capture sensitive French government and military data using Starlink.

“Four people were brought before the investigating judge for indictment, with two of them being remanded in custody,” the public prosecutor’s office said in a statement. Investigators are looking into possible acts of “delivering information to a foreign power or a company or organization under foreign control, or to their agents, in a manner likely to harm the fundamental interests of [France],” the statement added — a crime that can lead to up to 15 years in prison.

The prosecutor’s office said police had been notified last week that the arrested pair were suspected of conducting satellite interception operations from an AirBnB they had rented in the Gironde region, near the city of Bordeaux, after neighbors noticed that “a satellite dish approximately two meters in diameter” had been installed and local residents were experiencing internet outages.

“The device installed was used to illegally intercept satellite downlinks, including exchanges between military entities of vital importance,” the statement added.

On their visa application to enter France, the suspects said they worked for a company that focuses on “smart beams, signal recognition and satellite networks, and cooperates with universities establishing military-oriented projects.”
