LANHAM, Md. (CBSDC)- An Anne Arundel County teacher has been charged in relation to sexually explicit text messages she sent to a student, according to police.

Anne Arundel County police spokesman Justin Mulcahy said police began their investigation of 28-year-old Erin Nicole Thorne, of Arnold, after an anonymous caller told the public school system in November that there was a possible inappropriate relationship going on between the Broadneck High School teacher and a student.

According to police, the student in question graduated in spring 2011. During his senior year, he and the teacher formed a friendship. At one point, during the fall semester, police say Thorne began sending him sexually explicit text messages and they started talking on the phone. All of this, they say, occurred before he turned 18.

Mulcahy said that the two did have a sexual relationship but not until after the student turned 18.

Police obtained a warrant Tuesday for Thorne’s arrest on charges of displaying obscene matter to a minor and child porn solicitation, and she turned herself in to police around 1 p.m.

The charges combined carry a maximum of more than a decade in prison and $25,000 in fines. Bob Mosier of Anne Arundel County Public Schools said now that Thorne’s been charged the school system will move forward on firing her.
