Jordan Liu, a teenage babysitter Alhambra, California, was arrested over the sexual abuse of two young boys – after their mother discovered the abuse as she told her children about the Penn State Sex scandal.

Jordan Liu, 19, was accused of molesting the boys in his care after their mother found out while explaining to her eldest son what abuse was, using the example of Penn State football coach Jerry Sandusky.

Tom Lorenz, spokesman for the Glendale Police Department told ABC: “She was trying to describe some of the acts that are basically no-nos.

“The child began to cry and said, <<Mommy, the babysitter has been doing this to me>>.”

Jordan Liu was arrested on sexual assault charges for the abuse of an eight-year-old and a three-year-old last week.

The teenager entered a plea of not guilty to the charges on November 22 and was held on $2.7 million bail. His next court appearance is scheduled for January 5.

The mother of two made the horrific discovery after she was trying to educate her son about the dangers of child abuse from the Penn State scandal.

Jordan Liu was said to have been in charge of the boys for around four hours at a time at least once a month over the past eight months.

The family had found Jordan Liu on Sittercity.com, a website that matches families with babysitters.

Jordan Liu’s account has since been terminated. A company spokesman said it had been in touch with “anyone who may have had contact with him about the termination”.

Sittercity.com explained that it does background checks on members and cross- checked their identities with profiles on state sex offender registries.

Jordan Liu was also signed up to another site Care.com., which said he had been a member since 2008 and during that time in contact with “a little over 300 people”, but there was no way of knowing if he had worked for any of the families.

Police do not yet know if there are other victims of Jordan Liu, but the investigation is ongoing.

Jordan Liu’s Facebook profile has a picture of him holding a camera, standing next to a boy who appears to be a teenager.

Jerry Sandusky, the former Penn State assistant football coach has been accused of sexually abusing eight boys over a 15-year period.

Jerry Sandusky case also prompted three people to come forward with claims that Syracuse University’s basketball coach Bernie Fine sexually abused them when they were children.
