Police Commissioner Ram Singh said the incident took place in the evening when the boys began passing vulgar comments on seeing the girl, who was returning home after attending tuition classes.
The situation took an ugly turn when the boys followed her home where her parents rebuked them.
They then manhandled the girl and her family members besides threatening them of dire consequences if the matter was reported to police, Singh said.
The police official said of the total 11 accused, five have been identified and booked under various sections of IPC.
According to the family, the girl suffered a fracture in her right leg in the melee.
