In October 2026, the United States Department of Justice charged Wanying "Heather" Zhang (), a Chinese-American real estate agent in California, and others with having covertly surveilled and photographed Lai Ting-yu (), the son of Taiwanese President Lai Ching-te, and his family in a suburb of Seattle, Washington, in September 2025. In the criminal complaint, a Federal Bureau of Investigation (FBI) agent stated that Zhang had acted at the direction of individuals she understood to be officials of the government of the People's Republic of China (PRC), and that the residences, vehicles, and photographs of the president's close relatives could be of use to Beijing should it seek leverage over Taiwan's president in a potential conflict.
On October 4, 2026, Zhang was arrested by federal agents at Los Angeles International Airport as she was preparing to board a flight to Shanghai, China. She was charged with acting as an agent of a foreign government without notifying the United States Attorney General as required by law. She made her initial court appearance on October 5 with the judge ordered her held in custody, and a detention hearing was scheduled for October 7. Karen Kuo, spokesperson for the Presidential Office, condemned the incident as a typical, barbaric act of "transnational repression". Taiwan's Ministry of Foreign Affairs also strongly condemned the incident the same day and called on the international community to adopt countermeasures.
Background
Individuals involved
The principal accused, Wanying "Heather" Zhang, was 34 years old at the time and lived in Irvine, California. She held a California real estate license and worked for JC Pacific Capital (also known as JC Pacific Corp.), a local real estate brokerage. Zhang was from Changsha city in Hunan Province, China and citing a LinkedIn profile reportedly belonging to Zhang, the BBC reported that she had graduated from the University of International Relations in Beijing; Up Media, citing the criminal complaint, reported that U.S. investigators described the university as having close ties to the PRC's Ministry of State Security. Zhang later earned a master's degree in public administration from the University of Southern California, after which she remained in California as a real estate agent, promoting her business with the slogan "Southern California's ten-million-dollar agent". Data from real estate listing platforms show that she had handled more than 100 property transactions. Zhang lives with her husband, Edric Ding, who is also a real estate agent. The couple previously owned a home in Irvine valued at approximately US$6 million, which they sold in June 2026 before moving into a rental property in a nearby community. Zhang is a naturalised US citizen.
According to law enforcement sources, the espionage target was Lai Ting-yu, the eldest son of President of Taiwan Lai Ching-te, who was in his 30s at the time. He earned a bachelor's degree in electrical engineering from Case Western Reserve University and a master's degree from Johns Hopkins University, and later received a doctorate in bioengineering from the University of Washington. A long-time resident of the United States, he works as an engineer for the Dutch multinational electronics company Philips and lives in a Seattle suburb with his wife and son.
Political context and intelligence gathering
Since taking office as President of Taiwan as a member of the Democratic Progressive Party, Lai Ching-te has maintained that the Republic of China and the People's Republic of China are "not subordinate to each other". Beijing regards Taiwan as Chinese territory, has repeatedly denounced Lai as a "separatist", and has refused to hold official dialogue with his government. In the criminal complaint, the FBI agent assigned to the case wrote that, in pursuit of its political and strategic objectives, the PRC government might, in addition to strengthening its military posture, employ unconventional means to weaken Taiwan's will to resist. The complaint stated that if Beijing could obtain the exact addresses, vehicles, and daily movements of the Taiwanese leader's close relatives, such personal information could be used as leverage to pressure or politically coerce the president should the situation in the Taiwan Strait deteriorate or a conflict break out.
U.S. law enforcement officials also stated that PRC intelligence networks had previously carried out transnational operations targeting Taiwanese politicians and others abroad, and that the case was therefore not the first of its kind. U.S. authorities had previously found that Yaoning "Mike" Sun, acting on Beijing's instructions, had monitored former President Tsai Ing-wen's 2023 transit through Southern California; Sun was later sentenced to four years in prison. Authorities had also uncovered cases involving alleged covert overseas police stations. In addition, Czech military intelligence disclosed that personnel from the Chinese embassy in Prague had attempted in 2024 to follow and surveil Hsiao Bi-khim, then Vice President-elect, illustrating international precedents for such cross-border intelligence and surveillance operations.
Alleged surveillance
Contact and planning According to a criminal complaint filed by the FBI's counterintelligence squad in the United States District Court for the Central District of California, beginning in the first half of 2025 Zhang established contact with at least two people she knew to be employees of the PRC government. In January 2025, Zhang met "Chinese Official 1" for the first time; in June of that year, she was introduced to a second official, "Chinese Official 2", through an alumnus of the University of International Relations. She later traveled to Changsha, China, where she booked a private room to meet the official. During the meeting, the official raised a task involving "a house in the United States" and asked Zhang to carry out surveillance. She agreed on the spot and later sent a message saying, "I can handle this." On August 21, Zhang traveled to Hangzhou, China, to meet "Chinese Official 2" again. On August 26, she told the official via the messaging app WeChat that she was working in Los Angeles that week and expected to travel to Seattle the following week; the official replied, "Okay, thanks for your hard work."
Surveillance in Seattle
According to the complaint, on September 1, 2025, Zhang and a male associate identified as "Individual 1" flew from Las Vegas to Seattle, where they rented a black Nissan Rogue and drove to Lai Ting-yu's residence. The pair arrived near the residence at around 4:50 p.m. and began a stakeout. At around 6:00 p.m., Lai and his family had returned home, and the two allegedly used mobile phones to photograph and film the family. While "Individual 1" was filming, Zhang reclined the front passenger seat to lower her profile and avoid attracting attention.
The complaint states that during the stakeout, Zhang sent real-time updates to "Chinese Official 2" via WeChat, including the messages "Saw him, young male, it's the young one" and "I'm recording", along with two license plate numbers registered to the people under surveillance. The official responded with three "thumbs-up" emoji, and the two also held a voice call during this period. That day, Zhang also sent the official a video of the residence approximately 16 seconds long, in which her associate can be heard saying, "We're here, this is the house," and Zhang can be heard responding. At the official's request, she further reported that two cars were parked in front of the house and that an American flag was hanging there.
Tradecraft and evidence Fox43, citing the analysis of FBI Special Agent Kevin Holt in the charging document, reported that the conduct of Zhang and her associate involved several tradecraft techniques commonly used by foreign intelligence officers, including last-minute purchases of short-haul flights between different airports, renting vehicles for only a few hours before promptly returning them and deliberately using vehicles to conceal themselves as a countersurveillance measure. On September 8, 2025, Zhang asked "Individual 1" not to send the Seattle surveillance photos via WeChat or text message but to use AirDrop instead, saying, "I need to send the photos back; he wants me to send them back today." Investigators believe this was intended to evade digital monitoring and minimize traceable electronic records. U.S. law enforcement later obtained evidence of the surveillance and intelligence-gathering operation from security cameras installed by neighbors, as well as from WeChat conversations and photo files in Zhang's Apple iCloud backups, which were obtained under a search warrant.
Investigation and arrest
FBI investigation The complaint does not explain how the FBI first learned of the matter, nor whether the targets noticed the surveillance and reported it. The FBI's counterintelligence team subsequently obtained surveillance footage from around the targeted residence. After comparing footage from neighbors' security cameras, CBS News reported that the building shown matched the address of a property owned by Lai Ting-yu in suburban Seattle. Investigators then obtained a search warrant to search and seize the backups of Zhang's Apple iCloud account, from which they recovered complete records of the WeChat communications in which she had relayed real-time updates, photos, and license plate numbers related to the surveillance to at least two PRC officials.
Arrest at the airport and search of residence
On October 4, 2026, Zhang went to Los Angeles International Airport intending to fly to Shanghai. Before boarding, she was stopped by FBI agents, arrested, and handcuffed. FBI Director Kash Patel later confirmed the arrest in a post on X, sharing footage of Zhang being escorted in handcuffs. Patel wrote that the United States was no longer a safe place to conduct espionage, said that anyone who surveilled a foreign leader's family on American soil on behalf of the PRC and then tried to fly back to Shanghai would not succeed, and pledged that the FBI would pursue and bring to justice any threat to U.S. national security, wherever it might hide. Early on the morning of the arrest, about ten FBI agents wearing gloves raided the house Zhang was renting in an upscale neighborhood of Irvine, cordoning off areas including the garage to collect and secure evidence.
Legal proceedings
Following Zhang's arrest, the U.S. Attorney's Office for the Central District of California brought charges in the U.S. District Court for the Central District of California, accusing her of acting as an agent of a foreign government without notifying the U.S. Attorney General as required. The prosecution is being handled by Assistant U.S. Attorneys Amanda Elbogen and Colin Scott of the Central District of California, with Scott Lara of the Counterintelligence and Export Control Section of the Justice Department's National Security Division also appearing on behalf of the federal government.
On October 5, 2026, Zhang made her initial appearance at the federal courthouse in Downtown Los Angeles. She appeared in court wearing a white athletic jacket, black trousers, and white sneakers, with her wrists handcuffed and her ankles shackled. As proceedings began, her husband, Edric Ding, and an attorney accompanying him waved to her from the public gallery, and Zhang nodded in response; court officers removed her handcuffs before the judge began questioning her. Zhang appeared calm, speaking only to confirm her name and to state that she fully understood the charge against her; she did not enter a plea or make any substantive response to the charge.
