Kuldeep, the main accused, and his associates Rajesh and Vikram were arrested in connection with the murder of Ashok Saini who was found dead in Narela on January 28.
After investigation, police zeroed in on Kuldeep in the case as his family had issues with Saini and his father who happen to be his relatives.
"Interrogation revealed that Kuldeep had enmity with Ashok Saini due to land dispute, his arrogant behaviour and proximity of Ashok Saini with a girl of his village. Kuldeep was also having an eye on this girl," B S Jaiswal. Deputy Commissioner of Police, Outer District, said.
Since Rajesh was well known to Ashok Saini, Kuldeep asked Rajesh to call him to an isolated place near Red Quarters in Narela and allegedly murdered him.
