Nadia Christine Diaz was 24 when she had sex with the 15-year-old boy in January and February 2010, according to a statement filed by a police detective in court last week.

Diaz faces charges of sex with a minor and oral copulation after the alleged liaisons with the teenager from Washington Union High School in Fresno, California.

According to the Fresno Bee newspaper, the boy had asked his teacher for her cell phone number and soon their text messages turned to sex talk.

The boy told Detective Juan Galindo that he first had sex with Diaz in January 2010 at a friend’s house.

The next month, Diaz and the student met again at the friend’s home in the afternoon while the friend was at work to have sex.

‘The boy said they stopped talking after the second sexual encounter because rumors began to spread around the school that they were seeing each other,’ Detective Juan Galindo wrote in an affidavit.

These rumours prompted the school’s head teacher Principal Derek Cruz and District Assistant Superintendent Joey Campbell to confront Diaz last September.

When Mr Campbell identified the student, Diaz asked God to forgive her, according to the Fresno Bee.

Diaz is out on $60,000 bail and is scheduled to appear at Fresno County Superior Court on December 20.

Diaz’s lawyer Rick Berman insisted she has been the victim of malicious rumours.

Mr Berman said: ‘Nadia was arrested based on some rumours that the school district heard.’

District officials met with teachers at Washington Union to inform them of the situation and how to deal with questions from students.

Three additional counsellors were brought on to campus to support students.

The student said to have had sex with Diaz is now a senior at the school.

After being a substitute teacher, Diaz was later hired as a full-time science teacher at Washington Union High School. She has since resigned from her post.
