FREEHOLD, N.J. (CBSNewYork) – A New Jersey youth tennis instructor has been indicted on several charges of sexual assault and child pornography.

The Monmouth County prosecutor’s office said 26-year-old Terry Kuo, also known as Victor Lee, of Colts Neck, faces 15 counts, including attempted sexual assault, criminal sexual contact, manufacturing and possession of child pornography.

The investigation began when a 13-year-old tennis student came forward alleging multiple incidents of sexual misconduct over the summer and fall of 2017, authorities said.

Authorities said police found child pornography on Kuo’s electronic devices, as well as evidence of improper behavior involving other children.

Investigators are looking into whether there were additional victims.
