Security Breach at Taipei Dome: Guards Accused of Stealing Signed Memorabilia During Presidential Visit
In a breach of protocol that has left officials embarrassed and the public incredulous, members of the security detail assigned to Taiwan’s leader, Lai Ching-te, have been implicated in the theft of signed baseballs during a high-profile sporting event.
The incident occurred in February during a visit to the Taipei Dome for a “Taiwan-Japan Baseball International Exchange Game.” While the security team was tasked with ensuring the safety of the leader, one member allegedly used his privileged access to pilfer commemorative items from the venue’s restricted areas.
The “Locker Room Heist”
According to official reports, a security guard surnamed Jiang allegedly entered a locker room/break room during the event. Once inside, Jiang is accused of stealing six commemorative baseballs. These were not ordinary game balls; they were signed by professional players and members of the cheerleading squad, including the highly popular idol YunYun.

For those unfamiliar with the cultural landscape of Taiwanese baseball, YunYun (born Wu Han-chun) is far more than a cheerleader. She is a top-tier celebrity, variety show host, and entertainer, making her autograph a prized possession for collectors. The theft of items signed by such a figure has added a layer of public notoriety to the scandal.
Institutional Fallout and Legal Action
The discovery of the theft triggered an immediate internal investigation by Taiwan’s national security apparatus. The fallout has been swift and severe for those involved.
Jiang, who was a member of the Military Police Command providing support to the National Security Bureau’s (NSB) Special Service Center, was the primary suspect. Following the exposure of the theft, the NSB immediately stripped him of his support duties and referred him for legal prosecution.
The investigation expanded when officials discovered that the theft was not a solo effort. Two other security personnel were found to have been aware of Jiang’s actions but failed to report them. Under legal evaluation, these two individuals have been classified as accomplices.
The disciplinary actions for all three men include:
- Legal Prosecution: All three individuals have been referred to judicial authorities for criminal investigation.
- Professional Demerits: Each has been issued two “major demerits” (记两次大过).
- Career Termination: All three have been placed on a priority removal list for termination from their positions.
Security Integrity Under Scrutiny
The scandal reached the halls of government on April 13, when Tsai Ming-yen, the head of the National Security Bureau, faced questioning in the Legislative Yuan. During the session, Tsai admitted that the appropriation of private property by public servants during the execution of their duties is absolutely intolerable.
The incident has raised significant questions regarding the discipline and internal controls of the security detail. The fact that a guard could enter a restricted area to steal memorabilia—and that other guards would cover for him—suggests a lapse in the rigid discipline typically expected of presidential security.
Tsai Ming-yen emphasized that the NSB intends to strengthen legal education and internal oversight mechanisms to prevent similar occurrences. However, the incident has already dealt a blow to the image of the security system, highlighting a perceived looseness in management.
Key Takeaways
- The Event: A Taiwan-Japan Baseball International Exchange Game at the Taipei Dome in February.
- The Crime: Theft of six signed baseballs, including those signed by star cheerleader YunYun.
- The Perpetrators: One primary guard (Jiang) and two accomplices who failed to report the crime.
- The Penalty: Legal prosecution, two major demerits each, and placement on priority termination lists.
- The Source: The guards were from the Military Police Command supporting the NSB.
This case serves as a bizarre reminder of the intersection between high-stakes political security and the obsessive world of sports memorabilia. While the physical security of the leader was not compromised, the moral and professional security of the detail was clearly breached.

Official updates regarding the legal proceedings against Jiang and his accomplices are expected as the judicial investigation continues.
