Provoke for suicide?

Dear Puneet, Please do not only think about fame / defame, legal / illegal or other materialistic angles. Please think that the boy is just not being able to think of himself without your sister. Break ups are always painful. And more over if it's only because of the difference in CASTE, then within yourself please ask that what was his role in taking birth in a different CASTE. If the guy is good and if you think that he will be with your sister and love her forever, then yaar caste ko mariye goli. However, with due respect to both the families, at all if this is not possible to take forward then please communicate more and more in a compassionate way to the boy. His dreams of living life with your sister is getting shattered, he needs matured person too , as a elder brother who can make him understand and accept the fact of MOVING ON. Please put yourself in his shoes, you'll understand what to do and how to do.

Immediately your sister has to file a police comoplaint against that boy  

@fightingfalsecase Thanks for the suggestions and I understand your views. But my sister doest NOT want to marry that guy. Its as simple as that, what has caste to do with this? Why is he harassing and forcing her now?

@adv. rajeev ( rajoo ) Thanks for the valuable suggestion sir, my father is going to the SSP office to give a "tahreer". Is that different to file a police complaint? Kindly enlighten me with your views sir as I don't know much about legal terms.
