Two Nepali nationals were found murdered in their rented house in New Delhi on Wednesday morning, police said.
Bhola, 25, and Kartik Yadav, 24, were found murdered in their Mundka village house in outer Delhi, police said.
The police suspect their roommate, also from Nepal, to be behind the double murder.
Their heads had been smashed with an iron rod, which was recovered from the house, police added.
The duo used to sell Chinese food at a roadside stall in the area.
"We suspect that their third partner could have carried out the killings. Search is on to nab him," the police said.
The bodies of the deceased have been sent for post mortem examination and a case of murder was registered at the Mundka police station.
