'The couple eloped from the village some days ago and the girl's family registered a complaint against Sandeep Aug 5. We are investigating this case from all angles. Things will become clearer once we get the post-mortem and forensic reports,' added Saurabh Singh.
Police sources said injury marks had been detected on the couple's knees.
The incident comes close on the heels of another 'honour killing' where a young couple was allegedly beaten to death by family members of the girl in a village in Rohtak district Aug 6.
And last month, a 21-year-old man was lynched for marrying against the wishes of his community in Haryana's Jind district.
