The student’s mother told Channel 2 Action News that Brooks and her 17-year-old son had sex during off-campus tutoring. Brooks was his physical education teacher, she said.

The two had sex at least three times since October, including once at the student’s home while she was at work, his mother said.

In his letter, Johnson called the alleged inappropriate behavior between the teacher and student unacceptable.

“While this is not a situation we have experienced at our school previously, one time is too many,” he said. “Ethics matter, and the trust our community places in its educators matters to Archer and to Gwinnett County Public Schools. This is not something we take for granted.”

Brooks was released from jail on a $11,200 bond, jail records show.

The investigation is the latest in a string of sexual relationships between educators and students in the state’s largest school district.

In December, a former South Gwinnett High School band director pleaded guilty to sexually abusing four students in less than three years on the job. Villie Jones pleaded to 20 charges of sexual assault by a person with supervisory or disciplinary authority and was sentenced to 10 years in prison and 20 years of probation.
