CYPRESS, Texas -

A former Cypress Fairbanks ISD teacher is accused of having sex with a 16-year-old male student.

Kelly Thompson, 26, is charged with improper relationship with a student. According to court documents, the Cy-Lakes High School student admitted he had a sexual relationship with Thompson.

The boy allegedly told police they'd had sex in Thompson's car parked outside his house last April.

Investigators say Thompson claimed she and the boy were in love.

Thompson is also charged with tampering with a witness after police say she asked a friend to deny any knowledge of her relationship with the student.

The district released a statement which reads, "Cypress-Fairbanks ISD is very concerned about the serious nature of the allegations against a former Cy Lakes teacher. Inappropriate behavior or misconduct will not be tolerated by any staff member.  The safety of our students is always our highest priority and we will continue to cooperate fully with law enforcement."
