On June 22, the class 6 student apparently yawned during the morning prayer held in the private school, located on Mira Road in Thane. "The headmistress took strong objection to this and allegedly slapped the boy," Nayanagar's senior police inspector Balaji Pandhare said, quoting a complaint lodged by the student's father.
The boy's father also mentioned in his complaint that when he went to the school to enquire why the headmistress had slapped his son, she replied that if children indulge in mischief "we would punish them", Mr Pandhare said.
Based on the complaint, the police has registered offences against the school headmistress under section 323 - voluntarily causing hurt - of the Indian Penal Code, and also the provisions of the Juvenile Justice (Care and Protection of Children) Act, he said.
No arrest has been made so far, the official said.
"Out of fear, the boy was not ready to go to school on June 20. But, his father persuaded him to attend his classes and also complained to the school management about the headmistress," the police official said.
An investigation is being carried out, he added.
