SAN FRANCISCO: A Chinese researcher accused of concealing her ties to the Chinese military on a visa application was booked Friday into a Northern California jail.

Senior US government officials told CNN Friday morning that Tang Juan — who had hidden her status as a member of the People’s Liberation Army while working as a researcher at UC-Davis — had been taken into custody.

US media reports said that she was expected to appear in federal court Monday.

The FBI said on Thursday that she was being harbored within the consulate amid rising tensions between China and the United States over the theft of engineering and scientific research.

The Justice Department on Thursday announced charges against Tang and three other scientists living in the U.S., saying they lied about their status as members of China’s People’s Liberation Army. All were charged with visa fraud.

Tang was the last of the four to be arrested after the justice department accused the Chinese consulate in San Francisco of harboring a known fugitive.
