SANTA FE, Tenn. -- A former sixth-grade teacher is accused of soliciting a 14-year-old male student for sex.

SLIDESHOW - Teacher Arrested

Andrea Jill Rail, 27, resigned from her position at the Santa Fe Unit School on Monday and was arrested on Tuesday. She was released on $10,000 bond, but faces two counts of soliciting a minor.

Ex-Teacher Faces Child Sex Charges

Authorities said Rail allegedly asked a 14-year-old boy for sex and that the alleged incident happened sometime in the last school year.

The Maury County Sheriff's Department started investigating Rail after the teenager's mother contacted them.

Teacher Was Previously Reprimanded

A reprimand letter in Rail's personnel file reveals the principal of the school wrote a complaint about her relationship with the student in August 2005. At this time, Rail was instructed not to have contact with the boy.

However, in November during a middle school lock-in, the letter reads that Rail's actions were particularly disturbing because she was told to stay away from the student.

The letter does not get into detail about what allegedly happened, but Rail was once again ordered not to have contact with the student and forbidden to conduct school fundraisers.

The Director of Schools said they immediately informed Maury County detectives of this incident, but Rail was not fired because the school was told investigators could find no evidence of a crime.

Channel 4 has learned that e-mail conversations between Rail and the student are currently being examined by the district attorney's office. This data will be compared to information on Rail's home computer that is currently being analyzed by the Tennessee Bureau of Investigation.
