Authorities in Tennessee say they are investigating claims that a high school teacher in Memphis carried on a sexual relationship with a 16-year-old student.

According to the New York Post, the alleged victim is believed to have exposed the affair when 24-year-old Jasmine Edmonds failed to pay the $140 in blackmail he demanded.

The two allegedly carried on a sexual liaison at the teacher’s Raleigh apartment home.

The allegations surfaced publicly upon the publication by WHBQ of documents related to the investigation.

A text message from the unidentified teen, who had reportedly been Edmonds’ algebra student at Trezevant High School, informed the suspect that their “secret [is] going to be out there” if she fails to pay.

“That’s not a threat it’s a promise,” he allegedly wrote.

The teen reportedly followed up by demanding “140 tomorrow” or threatening to end her career.

Reports show the student had been expelled last year in response to claims that he had thrown rocks at Edmonds’ vehicle.

His mother reportedly offered a statement in connection with the investigation alleging that she “didn’t have any knowledge” that the boy and his teacher were engaged in a sexual relationship when she invited a lonely Edmonds to spend Thanksgiving with the family.

Court records also include a statement from the teen’s former basketball coach who claimed he saw the teacher waiting after practice on multiple occasions to pick up the student.

Edmonds was indicted in November on two criminal counts of sexual battery by an authority figure. She has since been released from jail after posting $50,000 bond, according to court documents.
