The police on Friday recovered the body of an Odisha-based manager working with a private coal company.
The deceased has been identified as Abhijeet who was here in town on official duty.
The police said the body was found in the bathroom of Ram Bhawan, stripped of all clothing.
Station house officer Mandi Gobindgarh Ajay Pal said the door of the bathroom was bolted from the inside and there was no trace of any external injury on the body.
Pal said the cause of death could be a heart attack.
He said no case of foul play was found during investigation, so the police have initiated inquest proceedings under Section 174 of the Code for Criminal Procedure and investigations are on to solve the case.
