Forney, Texas woman Charlotte Johnson says her 10-year-old son, Zye, was taped to a chair by his fourth grade teacher at Crosby Elementary School on Wednesday. “I’m very emotional. I haven’t had any sleep,” Johnson said. “That’s something you don’t do to a child.”

According to NBC News, Zye’s teacher grabbed him after the students’ lunchtime, led him to a chair, and instructed two of his classmates with helping to hold him still and grab tape. After taping his body down, leaving his arms grew, the teacher left the room to return the borrowed tape. In her absence, the two boys began hitting him over the head. Zye, who has dwarfism, raised his arms to shield his face.

“He’s 10, but he doesn’t look like he is,” she said. “He tells me one of the students told him, ‘I’m going to slap you as hard as Will Smith slapped Chris Rock.'”

When the teacher returned, Zye removed the tape went to an area designated for students to “cool down.” The teacher then made their over to him, claiming that they were “just playing.”

The teacher has since been placed on administrative leave, but no charges have been filed. The school district claims that the incident is still being investigated. Johnson, who hasn’t been contacted about the investigation, believe the teacher should be fired.

“My son was in your care, and you’re supposed to protect him from things like this, but it seems you’re only worried about the teacher,” Johnson said about the school district. “It looks to me you’re protecting the teacher, and you’re not worried about the well-being of my son.”
