The incident happened February 5, the Cumberland County Sheriff's Office said. Dawn Owen, a teacher at Ramsey Street High School, struck the victim on the head with a ruler, the sheriff's office said, and about 20 minutes later Owen grabbed the victim by the hair and walked her across the classroom to a bathroom area.
Detectives reviewed a video recording of the incident and conducted interviews before charging Owen with two counts of assault on a handicapped person.
Owen turned herself in at the Cumberland County Detention Center on Monday, where she received a $1,000 unsecured bond for the misdemeanor charges.
Her next court appearance is March 20.
