A New Jersey high school teacher has been arrested after she allegedly sent “inappropriate photos” to a student.

29-year-old Mallory Christ, a math teacher at South Plainfield High School, had sent two photos of herself to the student sometime in February of this year.

The investigation started after school officials learned of the photos being passed around on social media. They immediately contacted police.

The teacher and cheerleading coach has been charged with endangering the welfare of a child, and is being held without bail at the Middlesex County Adult Corrections Center in North Brunswick.

The investigation is ongoing, and anyone with information is asked to call Detective Clifford of the South Plainfield Police Department at (908) 755-0700, or Detective De La Cruz of the Middlesex County Prosecutor’s Office at (732) 745-3300.
