Shashi Kumar, the girl's father, in his complaint has named local youth Harpal, who went to his daughter who was playing outside their house and stuffed a 'sutli bomb' in her mouth and lit the fuse.
Her mother alleged that her three-year-old daughter got injured after a youth had set off firecrackers inside her mouth on Diwali eve.
The bomb exploded in the girl's mouth, causing serious injuries. She has received 50 stitches and her throat has also been infected, further compounding her health condition.
"Her tongue received a cut, her cheeks have burn marks and there are dust particles inside her mouth," the doctor said.
