Jennifer Forshey, 58, was charged with battery of a child by exposure to urine, according to an arrest report.
The teacher, who works at Broward Community Charter School in South Florida, was arrested earlier this week and later released on $1,000 bail. However she still insists that what she did was not illegal.
"I did not do anything illegal."
Police revealed that Forshey accused the boy of clogging the urinal with paper towels, before ordering him to use his hands and a paper towel to remove all the paper from the drain.
The child's hands were soaked in "what smelled like urine", officials noted, and it was also revealed that the boy had not been given safety equipment.
The boy told police the urine was not his and that he did not know who had clogged the urinal.
The victim's mother, Jenay Roberts, did not want to provide a statement, but her attorney released the following on her behalf:
"The only reason we are bringing this story to the public is to find out if any other child has been treated in this way before. We want to protect this child and possibly any other children that may have been subjected to this form or corporal and unmoral punishment.
"My client wants to find out why a teacher would allow this to happen"
"My client wants to find out why a teacher would allow this to happen. She also asks for her and her son's privacy to be respected and wants her son to retain a normal life back at the school."
The school has since revealed that Forshey will be reprimanded for her actions, but one co-worker, identified only as Debbie, has spoken up on her colleague's behalf, saying it was extremely out of character behaviour.
"She buys curriculum, she buys games. I mean, I've been with her when she buys all these incentives for the children.
"She was actually the main one to get us to like, you know, more positive reinforcement things like that."
