Police say an athletic trainer at an elite Catholic prep school recorded his sexual battery of a 16-year-old during an injury treatment, and they arrested him the next day.
Story Snapshot
- San Jose police arrested Archbishop Mitty High School athletic trainer Kelvin Chiu, 31, after a teen reported an assault and recording.
- Detectives seized phones and say they found video evidence consistent with the report, along with child sexual abuse material.
- Chiu was booked on suspicion of sexual battery and production and possession of child sexual abuse material.
- The school and diocese confirmed his employment, placed him on leave, and are cooperating with police.
Police Account: A Swift Report, A Rapid Arrest
San Jose police said officers were called at about 7:30 p.m. on October 8, 2026. A 16-year-old student reported that her school’s athletic trainer sexually battered her while treating a sports injury and recorded the assault on his phone. Detectives identified the trainer as Kelvin Chiu, 31, of Fremont, who worked at Archbishop Mitty High School on the 5000 block of Mitty Way. Police obtained search warrants and arrested Chiu in Fremont on October 9, the next day.
Investigators said they searched devices tied to Chiu. The San Francisco Chronicle reported that officers found video consistent with the student’s report on Chiu’s phone. Reports also said detectives found child sexual abuse material on the device. Police booked Chiu into the Santa Clara County Main Jail on suspicion of sexual battery, annoying or molesting a minor, and production and possession of child sexual abuse material. Authorities asked the public to contact them if they had information or knew of other victims.
School Response and Safeguarding Steps
The Diocese of San Jose said Chiu had worked at Archbishop Mitty since May 2025. The diocese’s communications director said the school placed him on administrative leave. Police said the school administration was notified and is cooperating with the investigation. The Chronicle reported the diocese said it had received no prior complaints about Chiu. That timeline matters for any review of hiring, reporting, and supervision practices inside athletic training rooms.
The school context raises familiar risks that demand tight controls. Athletic training involves authority, physical contact, and private spaces. Those features can be abused if leaders fail to apply strong policies and two-adult rules. Research on young elite athletes found about one in ten reported sexual abuse tied to athletics, with coaches named in a quarter of those cases. The same logic applies to trainers and health staff who see students one-on-one and may operate after hours.
What Police Say They Found on the Phone
Digital evidence often decides cases like this. Police sought search warrants for Chiu, his home, and vehicles. Reports said detectives located media on a phone that matched the teen’s account. The Chronicle tied the recovered video to the alleged assault report. Other outlets cited police statements that child sexual abuse material was also present on the device. Each description points to a core allegation: that the trainer recorded the abuse during a treatment session.
Law and common sense both say this: if a staff member records a minor during a sex act, that is not a gray area. It is a bright red line and a felony in every state. Americans expect schools to act at once when they see that kind of risk. In this case, police moved within 24 hours of the initial report. That speed reflects a proper priority on victim safety, device preservation, and campus risk control.
The Justice Track: Allegations, Due Process, and Parents’ Rights
Booking is not a conviction; prosecutors must still prove each charge in court. But parents deserve plain talk: a teen reported at once, police identified a named employee, obtained warrants, and reported finding video evidence. That mix of a prompt victim report and digital corroboration makes the case stronger than rumor. The law should run its course. The school should audit access logs, training room schedules, and supervision gaps now, not later.

Families want simple, hard rules they can check. Keep doors with windows. Require two adults or an open-door policy for every treatment. Log every student visit with times and staff. Train students to text a parent or coach before any one-on-one session. Post reporting contacts on the door. These are not expensive steps. They are basic guardrails that help honest staff and protect kids. When schools use them, bad actors have fewer chances to hide.
