The prosecutor’s office announced on July 25 that “a Canadian national of Chinese origin” had been arrested on accusations of espionage and participation in a criminal organization.

The suspect, who has not been named by the prosecutor’s office, worked as an intern at NATO’s Supreme Headquarters Allied Powers Europe in Mons, Belgium.

The office said she came to the attention of the organization’s security services, who reported the matter to Belgium’s military intelligence agency.

A federal source not authorized to speak publicly about the issue said officials in Canada were proceeding on the basis the suspect is Biwei Zhang — also known as Claire Zhang — who was previously employed by Canadian government agencies.
