"We have started our investigation and police are recording the statements of the family members. Also, the bodies have been sent for post-mortem examination," Madan Lal said.

Haryana is notorious for honour killings, with two cases being reported last month.
Two teenaged girls were murdered for having a romantic relationship with their cousin in Sonepat town. Three people, including a woman, were arrested.
In another case, a teenaged couple was murdered in a village in Bhiwani district by the girl's family as the boy and girl were from different gotra (sub-caste) and were planning to marry.
In March this year, a court in Karnal sentenced five people to death for killing a young couple who married in 2007 against the wishes of their community.
