The car was found abandoned in Pharal village in Kaithal district. Kaithal in Haryana is about 70 km from Nabha in Punjab where the jailbreak incident took place yesterday.
"A car has been found in the village. Further investigations were under progress," Kaithal's SP Sumer Partap Singh said, adding police and forensic experts were examining the car.
Another car had been found abandoned yesterday in Solumajra in Kaithal and is suspected to have been used by prisoners who escaped from the Nabha jail.
The car bore a fake Punjab registration number, he said.
Police teams from Punjab were called in for a coordinated investigation in the case.
Khalistan Liberation Front Chief Harminder Singh Mintoo, who had escaped from Nabha jail in Punjab along with five other inmates yesterday, was today nabbed from Nizamuddin Railway Station in Delhi.
