FALL RIVER, MASS. >> A substitute teacher at a Fall River middle school has been fired and could face assault charges for allegedly choking a 12-year-old student.

The resource officer at Talbot Middle School says when she responded to a special needs classroom on March 8 she observed the boy on the floor with the adult male — described as a paraprofessional — straddling his chest with his hands around the child's throat. The officer separated them and saw red marks on the boy's neck.

The adult wasn't arrested but was issued a summons to appear in court to face a possible assault and battery charge. Police did not release his name because he has not been formally charged.

School officials say the teacher was fired.

The student's mother says her son was traumatized.
