The Department of Justice has charged five individuals working on behalf of the People’s Republic of China (PRC) secret police for harassing and spying on Chinese nationals living in the U.S. who have “pro-democracy views.”

According to a report by Fox News:

DOJ arrested co-conspirators Fan “Frank” Liu and Matthew Ziburis on Tuesday and Shujun Wang on Wednesday Eastern District of New York. Two other defendants, including Qiming Lin and Qiang “Jason” Sun, remain at large, according to DOJ.

The “victims were targeted because of their pro-democracy views,” U.S. Attorney Breon Peace said during a Wednesday press briefing. Defendants are accused of “conspiring to act as agents of the PRC government,” he continued.

In one case, Lin attempted to derail the U.S. congressional campaign of a U.S. military veteran who was a student leader in the pro-democracy Tiananmen Square protests in China in 1989. Lin threatened to attack the candidate, among other crimes, in order to prevent his election to Congress, according to Peace.

In another case, Wang posed as “a well-known author and activist” based in Queens, New York, but abused his position to give information to the CCP.

In a separate case, three defendants including Liu, Ziburis, and Sun attempted to spy on and destroy the artwork of a Chinese national based in Los Angeles. The artwork was critical of the Chinese government.

The FBI is currently investigating the three cases.

Defendants face multiple charges, including conspiring to act as agents of the PRC government to commit interstate harassment and to bribe a public official.
