Kelvin Chiu
Introduction
Kelvin Chiu, 31, of Fremont, California, an athletic trainer at Archbishop Mitty High School — a private Catholic school in San Jose — was arrested on October 9, 2026, on suspicion of sexually battering a 16-year-old student he was treating for a sports injury and recording the alleged assault on his cellphone, according to the San Jose Police Department. Police said the student reported the alleged abuse herself, that a search of Chiu’s phone turned up child sexual abuse material, and that detectives are examining whether anyone else may have been victimized. Chiu was booked into the Santa Clara County Main Jail on suspicion of annoying or molesting a minor, sexual battery, and production and possession of child sexual abuse material; the allegations are suspicions in an active investigation, and nothing against him has been tested in court.
Background Information
Chiu worked on the athletic training staff at Archbishop Mitty High School, which police records identified through its address even though authorities did not publicly name the school in their investigation; the campus sits in the 5000 block of Mitty Way, where officers responded at approximately 7:30 p.m. on October 8. KTVU noted that while police did not name the high school, maps show one school on that block: Archbishop Mitty, a private Catholic school where tuition runs $34,000 per year and which is recognized for its strong academics and sports programs. The Diocese of San Jose, through communications director Cynthia Shaw, confirmed Chiu was a member of the athletic training staff and said the student’s family contacted school officials the night of the alleged incident.
The Controversy or Incident That Led to Their Cancellation
Arrested on suspicion of sexually battering a minor. San Jose police accuse Chiu of sexually battering a 16-year-old student-athlete under his care and recording the assault on his phone, with child sexual abuse material allegedly found on the same device. He has not been charged by prosecutors, has not entered a plea, and is entitled to the presumption of innocence.
Police say the assault happened on October 8, when the 16-year-old girl was under Chiu’s care for a sports-related injury; officers responded around 7:30 p.m. to the report of a sexual battery at the school on the 5000 block of Mitty Way. The teenager told officers that Chiu had been treating her for the injury when the alleged sexual assault occurred, and that he recorded it on his phone. Detectives with the San José Police Internet Crimes Against Children (ICAC)/Child Exploitation Detail Task Force secured warrants for Chiu, his home, and his vehicles; on October 9 they tracked him to his Fremont residence, searched the property, and took him into custody. Police said child sexual abuse material was found on Chiu’s phone, and he was booked into the Santa Clara County Main Jail on suspicion of annoying or molesting a minor, sexual battery, and production and possession of child sexual abuse material. Investigators reported no additional confirmed victims, but SJPD said Chiu’s position of trust has prompted concern that other students could have been affected, and the department asked anyone with information to contact its ICAC/CED detectives directly.
Public Reaction and Consequences
The Diocese of San Jose said Chiu was placed on administrative leave immediately after the family’s report and will not return to campus, and that the school is fully cooperating with law enforcement. Shaw said counseling teams would be available for students who need support: “Our first concern is for the student and family, and for all of our students and families. We recognize the impact a situation of this nature may have on our students, and the school’s Counseling teams will be available to speak with students who may need additional support.” The Diocese also encouraged any potential victim-survivors to come forward to report historic or occurring improper conduct, and KTVU’s coverage of the arrest, built on the SJPD press release and the Diocese statement, circulated the booking photo and the charges across Bay Area outlets within a day.
Current Status
Chiu was last reported in custody at the Santa Clara County Main Jail following his October 9 arrest; the Santa Clara County District Attorney has not announced filed charges, no arraignment or plea has been reported, and every allegation against him remains unadjudicated. The investigation is active: detectives are still examining whether anyone else may have been victimized during his time in the school’s athletic training staff, and SJPD has left open the possibility of more victims given his position of trust. The case will next move — if it moves — through the district attorney’s charging decision and the court system, which will determine what, if anything, is proved.
Impact on Their Career/Life
Chiu’s athletic-training career at one of the Bay Area’s most prominent private schools is over in practice: the Diocese says he has been on administrative leave and barred from campus since the night of the alleged October 8 incident, and no employer is likely to await the criminal process’s outcome before treating his employment as ended. For Archbishop Mitty — a $34,000-per-year Catholic school whose brand rests on academics and athletics — the case puts a member of its sports-medicine staff at the center of a child-sexual-abuse investigation, with counseling offered to students and the Diocese publicly soliciting any other victim-survivors to come forward.
