A Gwinnett County high school teacher from Georgia was arrested Friday for allegedly having sex with a 17-year-old student multiple times.

Sarah Katherine Brooks, 25, faced a felony count of sexual assault by a person with supervisory or disciplinary authority, according to jail records obtained by Atlanta Journal-Constitution. Brooks, who was a former physical education teacher at Archer High School was accused of having sexual encounters with the teen while giving him tutoring sessions off campus.

While she was supposed to be focused on the victim’s academics, the teacher allegedly had sex with the teenager at least three times at his house since October, when the victim’s parents were not present. Brooks “did, while employed as a teacher, engage in sexual contact with the victim, who said accused knew or should have known was a student enrolled at the same school,” the Gwinnett County police’s arrest warrant read, local news outlet Gwinnett Daily Post reported. 

Brooks, who was married at the time of the alleged encounters, resigned from the post after school officials were made aware of her alleged misconduct. On March 12, Archer Principal Ken Johnson penned a letter to the parents whose children attended the institution, informing them of the investigation that was launched into Brooks’ reported sexual involvement with a senior student.

“On Monday we received a report about this situation and our school immediately contacted the police and the school district's Division of Human Resources,” Johnson wrote in the letter. “As this has been and continues to be an active police investigation there are not many details I can share. However, I can tell you that the teacher has resigned from Gwinnett County Public Schools and the school system will be forwarding information about these allegations to the Professional Standards Commission.”

“While this is not a situation we have experienced at our school previously, one time is too many. 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. With that in mind, I thank you for your continued support of our school and its students,” he concluded.

References of Brooks on Archer’s athletics website were removed following her arrest. Not many details about the case were made public due to state laws protecting juvenile victims.

Brooks was booked into the Gwinnett County Detention Center on Friday afternoon and was released later on the same day on $11,200 bond.

In another instance, a former South Gwinnett High School band director, Villie Jones, pleaded guilty in December to sexually abusing four students while being employed. He was charged with 20 counts of sexual assault by a person with supervisory or disciplinary authority and received a 10-year sentence in prison and 20 years of probation.
