SUWANEE, Ga. – Gwinnett County Public Schools is besieged by teachers sexually abusing students, including at least four teachers arrested for inappropriate relationships in just the last week.

Derren Justin Evans, a long-term substitute teacher at Providence Christian Academy, was charged Wednesday with sexual assault based on allegations he repeated groped and kissed a female student, and also asked the teen to send him nude images on Snapchat, the Gwinnett Daily Post reports.

The student told officials the alleged harassment went on for weeks.

“As soon as the accusation was brought to us, Mr. Evans was removed from the classroom and placed on administrative leave,” Providence Christian head of school Sean Chapman told the Post.

The student alleges Evans, who is also a coach at the school, became progressively flirtatious during the school year before inviting her to lunch in his office on March 10. The teen told police she was surprised when she realized they were eating alone.

“She accepted, thinking others would be there since Evans shares his office with other coaches,” according to the police report cited by the Post. “When she arrived, only Evans was there. After she had sat down in a chair, Evans walked up behind her and began to rub her shoulders before kissing her neck. He then put his hands down her shirt and grabbed her breasts over her bra.

“She told him to stop and stated ‘I don’t want this’ before leaving.”

The student alleges Evans continued to grope and kiss her on several other occasions and demanded nude images over Snapchat when she insisted that he stop.

Evans’ arrest last Wednesday occurred at the same time Meadowcreek High School trach coach and health teacher Ronnie Jackson was bonding out of jail on similar sex assault charges, WSB-TV reports.

Police allege Jackson told a female student to meet him in the school gym to stretch her groin muscles before a track meet, and asked the girl he she wanted him to kiss her “boo boo to make it feel better,” according to a police report cited by Fox 5.

The girl agreed because she thought Jackson was joking, but he then kissed her three times between the legs, according to the police report.

One of the girl’s friends informed her parents, who contacted school and police officials.

On Friday, Parkview High School math teacher and assistant football coach Mikey Henderson resigned as he was arrested over a two-year long inappropriate relationship with a student, who is now 18 years old, the Atlanta Journal Constitution reports.

Henderson was a celebrated wide receiver for the University of Georgia Bulldogs from 2004 to 2007, and became a teacher at Parkview in July 2013. Friends of the student allegedly alerted authorities that Henderson had oral sex with a female student on multiple occasions since meeting the girl in his class.

Henderson denied the allegations at first, but later admitted to the relationship, according to the news site.

Those arrests followed the arrest of South Gwinnett High School band teacher Villie Jones Sr. the previous Thursday.

An 18-year-old student told Snellville City Police Jones raped her on numerous occasions, and also identified other students the 42-year-old band teacher allegedly had sex with, Fox 5 reports.

South Gwinnett High School Principal Monique Lee wrote in a letter to parents that “prior to his arrest, (Jones) submitted resignation to Gwinnett county Public Schools.”

Jones had worked at the school since 2014.
