WAKE COUNTY, N.C. — Wake County schools and local authorities are investigating an incident between a teacher's assistant and a student.

Dennis Ramsey said Samuel Stewart, a teacher's assistant at Martin Middle School, asked the boy to leave the room because he was talking out of turn in class. Ramsey said as he stood in the doorway at Martin Middle School, Stewart kicked the door, crushing the 12-year-old's hand.

"I screamed at him and asked him, why did he do that? Slam the door on me. He said I deserved it," Ramsey said.

It is not the first time Ramsey has had trouble with Stewart. In March, Ramsey said he hurt his head after Stewart pushed him down. His parents complained to the school, but they said nothing was done.

"I don't want to step foot back in the school," Ramsey said.

Doctors do not know if Ramsey will ever regain complete use of his hand.

School administrators will not speak specifically about the case because they said it is a personnel issue. They did say teachers are trained to handle classroom situations without anger.

"It's totally abnormal for us. It reflects badly on the profession. It's not indicative at all of who we have in our classrooms," said Michael Evans, spokesman for Wake County schools.

Stewart resigned the day of the incident. No charges have been filed.
