US authorities arrested a California woman on Sunday and accused her of spying on a son

US authorities arrested a California woman on Sunday and accused her of spying on a son of Taiwan’s president at the behest of Chinese officials, the FBI said.

The FBI arrested Wanying Zhang, also known as Heather, at Los Angeles International Airport on Sunday before her planned departure to China, the agency said in a statement. The agency did not directly name Zhang’s alleged target but later shared a New York Post report identifying him as Lai Ting-yu, a US resident. Authorities charged Zhang, 34, of Irvine, California, with acting as an unregistered foreign agent. The Justice Department said Zhang travelled to Seattle in 2025 at the direction of Chinese officials and subsequently sent them photos, video and licence plate information of the Taiwanese leader’s son and his family.

Zhang surveilled a son of Taiwanese President Lai Ching-te, the FBI said.

She will appear on Monday in a Los Angeles federal court, Essayli said. It was not immediately clear whether Zhang has a defence attorney.

Zhang used tradecraft to avoid detection and never notified Washington that she was acting for a foreign government, Bill Essayli, the first assistant US attorney for the Central District of California, said in a statement.
