FBI arrests woman accused of surveilling son of Taiwan's president

Wanying “Heather” Zhang stood at Los Angeles International Airport on Sunday, October 4, 2026, moments from boarding a flight to Shanghai when FBI agents moved in and put her in cuffs. She was 34 and lived in Irvine, California. The plane would leave without her.

Bill Essayli announced the arrest on X: “We just arrested a Chinese foreign agent at LAX attempting to depart for China...” Zhang faced a federal charge of acting as an unregistered agent of the People’s Republic of China. A criminal complaint, signed the day before by a member of an FBI counterintelligence squad and dated October 3, 2026, had already been filed against her.

“Zhang traveled to Seattle in 2025 and, at the direction of PRC officials, surveilled a close relative of a Taiwanese government official, sending photos, videos, and license plate information to those officials,” Essayli said. The relative stayed unnamed. The direction, he said, had come from officials of the People’s Republic of China. “She coordinated the trip with an associate and used tradecraft to avoid detection. She never notified the Attorney General she was acting for a foreign government, a federal offense.” Anyone acting inside the United States for a foreign government is required to register with the Attorney General; she had filed nothing. The FBI stated the boundary in one sentence: “Foreign intelligence operations cannot be carried out on U.S. soil and simply get on a plane back home.”

Zhang and a man listed only as Individual 1 flew from Las Vegas to Seattle on September 1, 2025. On the ground they rented a black Nissan Rogue and drove it to the suburban home near Seattle that belonged to their surveillance target. Law-enforcement sources identified that target as Ting-Yu Lai, the son of Taiwanese President Lai Ching-te.

A neighbor’s security camera recorded the arrival. Footage included in the criminal complaint allegedly shows Zhang and the associate appearing to film and photograph Lai, his wife, and their child as the family came home that evening. The child was caught in the neighbor’s frame with the parents.

Zhang used the Chinese messaging app WeChat to reach her handler. Those messages were later obtained through a search warrant on her iCloud account. FBI Special Agent Kevin Holt set them out in his October 3 affidavit. She told the handler she had spotted the target and was recording video. The complaint quotes the exact lines: “Saw him. Young male. It’s that young one.” “I am videorecording.” She sent two license plate numbers.

In June 2025 Zhang booked a private room in Changsha, China, during a trip. A classmate from Beijing’s University of International Relations, her alma mater, introduced her there to a Chinese official. Holt’s affidavit ties the university closely to the Ministry of State Security. The official gave her the surveillance assignment in that room. She texted him afterward: “I can take care of this thing.”

On August 26, 2025, she wrote again: “I will be busy with work in L.A. this week. I will probably go to Seattle next week.” The official replied, “Ok. Thank you for your hard work.”

Zhang was a licensed California realtor with JC Pacific Capital in Irvine. Her husband, Edric Ding, worked at the same firm.

Ting-Yu Lai earned a bachelor’s in electrical engineering from Case Western Reserve University in 2012, a master’s in Bioengineering Innovation and Design from Johns Hopkins in 2013, and a PhD in bioengineering from the University of Washington. He works as an engineer at Philips, the Dutch multinational. He married his Taiwanese wife, Hsiao Chen, in 2018. They had a child in the United States in 2020.

Holt’s affidavit set out why the images and plates could matter. The location and pictures of close relatives of a high-ranking Taiwanese official—homes and cars included—could give the People’s Republic of China leverage over Taiwan’s president in any potential conflict. The Foreign Agents Registration Act requires a person acting inside the United States for a foreign principal to register with the Attorney General and disclose the relationship; the charged offense is the failure to register.

Kash Patel said: “Allegedly monitoring the family of a foreign leader on U.S. soil for the People's Republic of China and trying to catch a flight back to Shanghai? No way.” He added: “Allegedly surveil a foreign leader's family on US soil for the PRC – and try to catch a flight back to Shanghai? Not happening.”

Bill Essayli said the next step would come in open court. “She will appear in federal court in Los Angeles tomorrow for her initial appearance. Defendants are presumed innocent until proven guilty.” The initial appearance was set for Monday in Los Angeles federal court. Whether she had counsel was not clear.

Edric Ding said, “I don’t know anything yet.” He declined further comment.

The Shanghai flight left without her.
