The girl, a resident of Beli Road locality, alleged that the youth had been teasing her almost every day while going to college, and then she decided that enough was enough.
On Friday, the girl caught hold of the youth, and as the latter left his bike and began the run, the girl hurled abuses at him, and then proceeded to set his bike on fire.
Later police came to douse the fire, but by then, the vehicle was completely gutted.
