The body of Dilawar (62), who resided in Indirapuram area of Ghaziabad, was found in car parked near a school late last night, they said.
Dilawar worked as a manager in a hotel at Sector 8.
Prima facie it appears that few persons attacked and killed when he was returning to his house, a senior police officer said, adding cash and other goods kept in the car were not looted.
Two days back, some customers had threatened the manager of dire consequences after a clash with the hotel staff, he said.
