The girl’s mother, Anita Yadav, and her paternal aunt Rinki Yadav were apparently annoyed with the minor for playing in the house and creating mischief, Kalamboli police station’s senior inspector Satish Gaikwad said.
They allegedly burnt the child with candle, causing injuries all over her body, he said.
The girl’s father, a vegetable vendor, on Wednesday lodged a complaint, based on which the two women were booked under relevant provisions of the Juvenile Justice (Care and Protection of Children) Act, the official said.
No arrest was made so far, he said, adding that a probe was underway.
