The video clip of the teacher slapping and dragging the child has gone viral on the social media.
The child said as he was engrossed in drawing, he could not respond to the roll call by the teacher.
The incident came to light when the student reached home from school yesterday and his parents noticed that his face was swollen and he was behaving in an unusually dull manner, the police said.
The parents then met the school principal, who checked the CCTV footage which purportedly showed the teacher, Retika V John, mercilessly slapping the child and dragging him.
The principal then called the teacher, who tendered her apologies. The parents were assured that her service was being terminated.
Following a complaint by the child's father, an FIR was today registered against the teacher for voluntarily causing hurt, Station officer of PGI police station Brijesh Rai told PTI.
