A 30-year-old man, Kuldeep Singh, was arrested from New Delhi railway station for allegedly murdering two sisters at their home in Sector 22. The victims- Manpreet Kaur (28) and Rajwant Kaur (27) – were running a small pharma company in Zirakpur. Police said that Kuldeep was in a relationship with Manpreet, but for the last few months the latter was not in good terms with the accused. Kuldeep was under the impression that the woman was in a relationship with someone else. Kuldeep stabbed both the sisters after he entered the house to check the cellphone of Manpreet. Besides, Kuldeep also assaulted them and strangulated both the sisters with a dupatta.
