A club owner Sanjeev Joshi went to the Knite Ryder club in Gurugram  DLF Phase-3 with three other friends for a party.

They booked a hotel room for the night. In the morning two of them were found dead and two others were critical.

The police said they are looking at all angles, including murder and death by accident.

The cause of death is currently stated as suffocation.

The four friends were celebrating Joshi's birthday inside a room with a fireplace.

They ordered food, went inside the room with the fireplace and spent the night there, the police said.

On Monday morning, the club's staff found them all unconscious.
