Mann was charged with harassment on Friday morning by Chester police. It is a summary offense and Mann was given paperwork to appear in court at a later date.
The fight happened back on March 14th inside a classroom at Chester High School. Police said, at the time, they had cell phone video of the incident.
The teacher involved, Leslye Jordan, spoke to Action News the day after the incident.
She said Mann came to her classroom demanding to speak to her about a critical letter Jordan had written to the superintendent.
Jordan says the discussion turned into a shouting match and, when she tried to leave, Mann slugged her in the face.
"I tried to walk away to get someone to witness the way she was acting because I've known in the past that you don't want to be in a room with someone by yourself," said Jordan.
The fight spilled out into the hallway in front of startled students. Jordan has been treated for cuts to her face and a banged up elbow.
Mann has told investigators that Jordan threw the first punch. Action News tried to ask her about it outside her home in Chester, but she walked past our crew with no comment.
