The deceased has been identified as Pappu, they said.
Pappu's family members had informed the police about his sudden demise yesterday, SHO Loni border police station Virender Yadav said.
Although, when the police team reached the spot they found no marks on the body, he said.
Doubtful over the family's story, the police have sent the body for postmortem, Yadav said.
"No FIR has been registered at the police station as family members have not filed any complaint. We are awaiting the final outcome of postmortem report after which it could be ascertained whether Pappu died of natural death or was killed," the SHO said.
