She said she was told her son was charged for striking the teacher in an insulting or provoking nature.
“I was very shocked,” she told Channel 2.
Coleman, who is a graduation coach, is charged with simple battery but was not arrested, according to Atlanta Public Schools spokesman Seth Coleman. The school district also confirmed the charge against Koonce.
The teacher did not speak with Channel 2 about the incident.
After making a hospital trip for injuries, Koonce now wants his charge dropped, and tough punishment for Coleman.
“I don't think he should be working there around any students,” Koonce said.
