He was injured and had a heated argument with the young woman in the car.
The boy claimed he was accused of sexual harassment by policemen standing nearby and was paraded half-naked on the streets by them.
'They forcibly removed my shirt, tied my hands with it and wrote insulting remarks on my chest and back. Then I was forced to parade through various localities,' the teenager told reporters.
The policemen have been accused of taking his shirt off and writing 'Main ladkiya cherta hun' (I molest women) on his back and chest.
It was only after some local journalists intervened that the policemen set the teenager free.
