Blood spilled all over and within two seconds everything was over."The young woman has said Ankit and she planned to get married soon. "I was going to meet him and then someone told me he had been stabbed with a knife. We were going to marry. He called me and told me he wanted to marry me, so we were meeting," she told reporters.The two began dating when they were neighbours a few years ago. They continued the relationship even after her family moved away.

"During the investigation, we found that they caught and stabbed Ankit in the neck. The woman's family was against their relationship as they belonged to different communities and had warned Ankit against associating with her," senior police officer Vijay Kumar said.The young woman, who the police say is in a state of shock, is with the cops right now for safety reasons. The police said she will be produced before the Child Welfare Committee so that a decision could be taken where she will stay. She had told reporters that she was "scared of her family".
