MVPD seeking additional victims in child sex assault case

We are seeking the public’s assistance in helping additional victims come forward after MVPD officers arrested a Cupertino man this weekend for lewd and lascivious acts against children.
On Friday, Feb. 2, officers received a call from a parent who stated that their son had informed them that a volunteer at Sanyu Learning Center, located at 1425 S. Springer Road, touched him inappropriately over several months while the victim attended the after-school program. While speaking with the first victim, officers received a call that a second victim had come forward and stated he had also been inappropriately touched by the volunteer. Officers followed up, and learned that the victim was also an attendee at the after-school program. 
That night, we quickly began working to locate the suspect, 26-year-old Cupertino resident Yizhuang “John” Liu. The suspect was not only a volunteer at the Sanyu Learning Center, he also served on the center's board of directors. 
Liu was located early on Saturday, Feb. 3, and was subsequently booked into the Santa Clara County Jail on six counts of lewd and lascivious acts with a child under 14 years old, two counts of lewd and lascivious acts with a child under 14 years old with force and one count of continuous sexual assault over a period longer than three months.
During their initial investigation, our officers learned that in addition to interacting with students at the Sanyu Learning Center, he also communicated with potential victims on a gamer’s social media application known as “Discord.”
We are extremely concerned there may be additional victims in this case, and we are asking that anyone who may know of additional victims to please reach out to Mountain View Police Detective Marco Garcia at or Sgt. Chris Goff at 
Sanyu Learning Center personnel are working with the Mountain View Police Department and are cooperating with the investigation. Because this is an ongoing investigation, for updates, please check with the Mountain View Police Department on Facebook, Twitter or Nextdoor.
