A Harlem high school teacher was charged with assault for manhandling 17-year-old student who wouldn’t get off her cell phone, cops said.

The teacher, 44-year-old Abdu-Allah Torrence, asked the student to stop using her phone, and then grabbed her by the back of her neck and pulled her backwards when she didn’t do as he asked, according to police.

The student was taken from the Thurgood Marshall Academy for Learning and Social Change on W 135th St. to Harlem hospital at about 4 pm Tuesday, investigators said.

She was treated at the hospital and released.

Torrence was issued a desk appearance ticket for misdemeanor assault.
