A teacher has been charged with assault after a video showed her dragging a 9-year-old boy with autism through the halls of a Kentucky school.

Kentucky State Police “opened an investigation into teacher Trina Abrams,” Senior Trooper David Boarman said, adding she has “been charged with Assault 4th Degree, victim under 12 years old.”

Abrams pleaded not guilty to the charge during her arraignment Wednesday.

The Greenup County School District on Monday announced the termination of a teacher, whom it did not name, more than two months after the October incident, CNN affiliate WSAZ-TV reported.

“The teacher was removed from the school and a formal investigation was conducted,” Superintendent Sherry Horsley said in a statement to WSAZ. “The superintendent also followed protocol and reported the incident to the Kentucky Education (Professional) Standards Board.”

Matthew Wisecup, Abrams’ attorney, said his client “maintains her innocence … and intends to fight this charge in court.”

The boy’s mother, Angel Nelson, told CNN on Monday that her son was removed from a classroom after he had an outburst.

Video from the school’s cameras, which Nelson shared on Facebook, appears to show a woman dragging a young boy by the wrists through the school’s hallways. At different points in the video, the boy is either lying on his back or sliding on his knees.
