Cops arrested a 65-year-old teacher’s assistant at a Brooklyn school for allegedly getting rough with an 8-year-old girl.

In an attempt to reprimand the mischievous pupil, Saka Rafiu threw a punch before he smacked and shoved her, cops said.

The youngster was acting up in class and made contact with the teacher’s aide before he retaliated with the physical contact, according to cops.

Rafiu was charged with endangering the welfare of a child. No injuries were reported.
