A San Jose State University graduate student was arrested after investigators say he left a trail of racist bomb threats in campus restrooms.
Quick Take
- Federal authorities say the student posted false bomb threats and hateful messages across campus bathrooms.
- Investigators say the messages disrupted university life for months and forced repeated emergency responses.
- Authorities say a fingerprint, key card records, and surveillance video tied him to the messages.
- The case fits a wider pattern of bomb threats at schools that often prove to be hoaxes but still trigger major disruption.
What Authorities Say Happened
Federal prosecutors say Ziheng “Tony” Fang, 30, of San Jose, posted threatening messages in men’s and gender-neutral restrooms at San Jose State University beginning in October 2024. The messages allegedly included threats of bombs, shootings, and other violence, along with hate symbols aimed at several racial and religious groups.
According to the criminal complaint, investigators found Fang’s fingerprint on one of the messages. They also say his university key card placed him inside buildings before many of the messages appeared, and surveillance video showed him near the restroom areas where several were later found.
Why the Case Stood Out
This was not a single panic-inducing note slipped under a door. Prosecutors say campus police documented more than 20 threatening messages over a long stretch, from October 2024 through May 2026. One message found on November 5, 2025, warned of a mass bombing the following week.
That detail matters because repeated threats change the whole equation. Universities cannot treat a bomb threat as casual speech when students and staff are hearing warnings again and again. Even when no explosive is found, the disruption can shut down classrooms, empty buildings, and keep everyone guessing about the next message.
How Campus Life Gets Upended
Authorities say the threats pushed the university into repeated emergency alerts and forced some professors to cancel in-person classes or move them online. Campus police also received many calls from worried students and employees, while the buildings named in the messages were largely empty on the dates mentioned.
That is the hard truth of these cases. The damage is not only about what might have exploded. It is also about fear, lost class time, shaken confidence, and the long, expensive response that follows every threat until police decide it is fake.
A Wider Pattern of Hoax Threats
The San Jose State case sits inside a broader pattern of false bomb threats aimed at schools and universities. Educational institutions remain a frequent target, and many recent threats have turned out to be hoaxes that still caused lockdowns, evacuations, and police searches.

That pattern helps explain why law enforcement moved so aggressively here. Officers do not need a real bomb to justify a serious response. A written threat in the wrong place, especially one tied to hate and repeated over time, can be enough to bring federal charges and a major investigation.
What the Arrest Means
Fang was charged with false information and hoaxes, according to the Department of Justice report cited in the case materials. He remained in federal custody after his initial court appearance.
The case is a reminder that a restroom wall can become a crime scene in minutes. A single message may look like vandalism at first. But when it carries a bomb threat, a racial edge, and a pattern of repetition, prosecutors treat it as something far more serious than a bad joke.
