The victim was staying in a rented accommodation in Ajaybag area of the city. Police have ruled out murder.

Meanwhile, Ashish Chaturvedi, the whistle-blower in the Vyapam episode, in his Facebook post claimed Bhurelal Vaskel was linked to the scam. However, police did not confirm Mr Chaturvedi's claim.
