A 33-year-old labourer was arrested along with his wife for allegedly killing a man in southwest Delhi's Jaffarpur Kalan area, police said on Thursday.
The accused has been identified as Daulat Ram, a resident of Hathras in Uttar Pradesh, they said. According to the police, the deceased was in a relationship with Ram's wife and was pressurising the woman to elope with him.
On Tuesday, Jaffarpur Kalan police station received information that a body had been found in a drain. The police reached the spot and found the body. The deceased had an injury mark on his left temple, police said.
The deceased was identified as Sonu, a resident of Pandwala Kalan. He used to work as a labourer, police said.
During the investigation, it was found that Ram who was known to Sonu was absconding. It was found that Ram, along with his wife and, children had left his room, Deputy Commissioner of Police (Dwarka) Shankar Choudhary said.
On Wednesday, the police apprehended Ram after he returned to his room to take his belongings, the DCP said. The accused disclosed that he knew Sonu for the last 17 to 18 years. Both worked as labourers in Delhi, police said.
