The French offices of Chinese tech giant Huawei were searched this week, the company confirmed Friday, saying it was fully cooperating with the authorities.

A French judicial source told CNN Thursday that the raid had been carried out as part of a preliminary probe launched by the financial prosecutor’s office over alleged “breach of probity,” a broad term concerning offenses such as acts of corruption, favoritism and influence peddling.

The source did not provide any further details about the investigation. A preliminary investigation does not imply any wrongdoing.
