San Francisco – A Chinese scientist accused of hiding her ties to the army of China In her application for a visa to work in the United States, she was booked in a prison in Northern California and is scheduled to appear in federal court on Monday.

Sacramento County jail records show that Juan Tang, 37, was jailed on behalf of federal authorities on Friday after being arrested by agents of the United States Federal Marshals Service (USMS). It is unknown whether the detainee had an attorney who could offer statements on her behalf.

The Justice Department on Thursday announced the charges against Tang and three other scientists living in the United States, noting that they lied about their status as members of the Chinese People’s Liberation Army. All were accused of fraud to obtain the visa.

Tang was the last of the four people to be arrested after the Justice Department accused the Chinese consulate in San Francisco of housing a person known to be a fugitive. The consulate did not immediately respond to an email or Facebook message seeking comment, and it was impossible to leave a phone message.

The Justice Department claimed that Tang lied about his military ties in a visa application last October when he planned to work at the University of California at Davis, and again during an interview with the FBI months later. Agents found photos of Tang dressed in a military uniform and reviewed items in China that identified his military affiliation.

The University of California at Davis noted that Tang left her job as a visiting researcher in the Department of Radiation Oncology in June. Her work was funded by a study exchange program affiliated with the Chinese Ministry of Education, the university said in a statement.
