Delhi police have arrested the parents of Bhawna Yadav who was strangled and later cremated, for marrying a man against her family's wishes. Last week university student Bhawna married Abhishek Seth, 24, who works as a computer programmer at the Rashtrapati Bhavan. They belong to different castes and had met at a party. Bhavna Yadav, 21, was allegedly killed by her parents in their apartment in Delhi then cremated at the family's native village in Alwar, Rajasthan. Seth's mother said the two families met after her son came home with his new bride, but Bhawna's parents were angry so she tried to reason with them. Reports say Bhawna's parents requested she be sent back home so they could organise a wedding with proper ceremonies, and when she did return home her parents allegedly told her they had gotten her engaged to another man. The next morning Seth's family received a call informing them Bhawna had died. Police say the parents who strangled her initially told them she died of snake bite, but they later confessed to the crime. Honour killings are not uncommon in India where many still prefer arranged marriages within their own caste.
