"It's terrible, and we don't want anything like that to happen to any other children," Amber Tilley told NBC Dallas-Fort Worth.

According to the lawsuit, the incident left the boy "visibly and severely distraught," and he had to see a therapist after.

"He just kept on and on, wanting to take baths," Amber Tilley said. "You know, he just felt so disgusting."

She added that her son did not have a problem with body odour or cleanliness.

The school district and Peaster Elementary did not respond to calls for comments Friday.
