A former teacher at a private Catholic school in Westchester has been charged with raping a 14-year-old student earlier this year, prosecutors said. 

Authorities say 27-year-old Amanda Iles was a teacher in the religion department at Archbishop Stepinac High School in White Plains when she allegedly engaged in sexual encounters with the student between June and July. 

Prosecutors say the encounters were not on school grounds. 

The victim's parents called police when they learned of the encounters.

Iles returned to New York Wednesday morning from California, where she had recently been living, and surrendered to police. It wasn't known if she had an attorney.

Stepinac High School said that Iles was employed during the 2012-13 school year and resigned in June. The school said the alleged sexual encounters occurred after the school year had ended. 

"We are deeply concerned with matters involving the well-being of our students who are our top priority," the school said in a statement. "Stepinac has and will continue to fully cooperate with any investigation into this matter."
