Martial Arts Instructor Arrested in Riverside County

A martial arts instructor in Riverside County has been arrested on multiple sexual assault charges involving a minor student.
Investigators say they believe there may be additional victims and are asking anyone with information to come forward.
What Led to the Arrest
Riverside County deputies identified the suspect as Dzung Mai, 62, of Temecula, according to KTLA's reporting on the case.
The investigation began after a victim reported being sexually assaulted during a martial arts lesson with Mai, prompting Riverside County deputies to open a formal inquiry.
Mai had reportedly been teaching martial arts at his home for several years, instructing students ranging in age from 5 to 19.

What Happened When Deputies Acted
Following the investigation, deputies served a search warrant at Mai's home in the 31000 block of Iris Way on June 26, where he was taken into custody.
He was booked into the Cois Byrd Detention Center on multiple sexual assault charges. The Riverside County Sheriff's Office has not released further detail on the specific counts filed.

Why Investigators Are Asking the Public to Come Forward
The scale of Mai's teaching history is central to why the case may extend beyond a single reported incident.
Years of in-home lessons across a wide age range means investigators are now working to determine whether other students may have experienced similar treatment, a process that depends heavily on people coming forward voluntarily.
The Riverside County Sheriff's Office said: "This investigation is active and ongoing, and no further information will be released at this time," a standard posture in cases where releasing additional detail could compromise the integrity of an expanding inquiry.
What Happens Next
Anyone with relevant information has been asked to contact Investigator Andrade at 951-955-2777 or Investigator Roberge at 951-696-3000.
Mai's case remains in its early stages, with no court date publicly confirmed as of this writing, and the Sheriff's Office has given no indication of when additional information might be released.
