Commissioner of Police (southeast) Chinmoy Biswal said the police received a PCR call at 5 am on July 6 by Singh’s brother.
Police suspect that Singh was killed by unidentified assailants on the intervening of Friday and Saturday.
Officials said Singh's brother found his body and reported it around 5 am on Saturday. He also told police that Singh had returned home late from work after meeting his colleague.
On reaching the spot, the victim was found with stab injuries on his back.
He was taken to a nearby hospital, where he was declared brought dead, the officer said.
The post-mortem was conducted at AIIMS after which the body was handed over to the family, the officer added.
Singh's 16-year-old son, Pradeep, told police that his mother woke him up at around 3 am and told him that his father is lying in a pool of blood.
He had come home late on Saturday night. His children had slept by then. When his mother informed him, he woke up his uncle, Mukesh, who was sleeping in the same room where the children slept, the son told police.

During preliminary probe, it surfaced that the family kept the house gate open due as it was hot inside. Singh came home around 11 pm, had dinner and slept in his room while his wife, kids and brother-in-law were in a separate room.
Around 3 am, the wife woke up to urinate when she found blood oozing out of the body of Singh, police said.
