KATY, Texas -

A former technology camp instructor has been accused of having inappropriate contact with a second child.

Harris County sheriff's deputies said Anthony Tang, 38, is facing two new charges of indecency with a child. In late March, he was charged with sexual assault and indecency with a child.

About two years ago, Tang worked as a manager at Camp Katy Technology Camps and attacked a 14-year-old boy, according to deputies.

Shortly after KPRC Local 2 and other media outlets reported that story, a second child, now 15 years old, came forward, investigators said.

Tang had posted bail on the original charges, but he was arrested on the new charges on Friday.

Investigators said they suspect Tang may have had inappropriate contact with other boys.

Anyone with information is asked to call the Harris County Sheriff's Office at 713-830-3250 or Crime Stoppers at 713-222-TIPS.
