Police authorities said that the reason behind the attack was because of a one-sided affair, which the girl had rejected earlier.
The vicitm has been admitted to Patna Medical College Hospital (PMCH) for adequate treatment, while the accused, Sonu has been arrested on Tuesday within 12 hours of the incident.
It so happened that when the girl, who was walking down the street with her maternal uncle, was attacked by Sonu while travelling with his friend on a bike.
