Theresa Hrindo, 25, is charged with two counts of sexual assault, two counts of endangering the welfare of a child, and one count of hindering apprehension.

Hrindo, of Linden, engaged in sexual acts with the student at several times and locations in Union County from December through February, the prosecutor's office said.

She is charged with hindering apprehension because she deleted incriminating photos and files from the student's phone, authorities said.

Hrindo graduated from Roselle Catholic in 2010 and Kean University in 2014.

She was arrested at her home Thursday and has a detention hearing scheduled for Friday afternoon.

The Archdiocese of Newark, which has jurisdiction over Roselle Catholic, reported the sexual relationship to the prosecutor's office, leading to a three-week investigation, authorities said.

Jim Goodness, a spokesman for the archdiocese, said Friday that the archdiocese and the school suspended Hrindo when they heard about the alleged sexual acts a few weeks ago. The school alerted staff to the allegations and are in the process of advising parents.

"This is certainly something we're very concerned about, and we don't accept this kind of behavior or action," Goodness said. "It's very clearly against all school and diocesan policies, and plus, it's against the law."

A phone number listed for Hrindo was not in service.

Authorities ask anyone with additional information to call prosecutor's office Detective Brian O'Malley at 908-220-4323.
