A family of three, including a four year-old boy, from west Delhi's Rohini was charred to death when their car caught fire on Mathura Road, in the wee hours of Thursday.
The family was on its way to Vrindavan, Uttar Pradesh, when the accident took place at 2.40am.
The Bansals — Lokesh, 30, his wife Ritu and son Garvit — had reached Alwarpur in Palwal, Haryana, when their CNG-powered Maruti Zen Estilo hit an oil tanker from the rear, leading to the fire, police said.
The Bansals lived in Unique Apartments in Sector 13, Rohini. They had left their house at 12.30am. Preliminary investigations suggest that the Bansals, who were trailing the truck on National Highway-2 in high speed, rammed into it when the truck braked suddenly.
"After rushing to the spot, we tried to douse the flames with two fire tenders," said Abbas Khan, station house officer, Camp Police Station, Palwal. "The doors of the car had to be cut open as they got jammed because of its central locking system. The bodies were charred beyond recognition," Khan added.
The police have registered a case against the truck driver, who fled the spot and whose identity could not be established.
Lokesh Bansal's elder brother, Vivek, told Hindustan Times that the fire was the result of an explosion in the petrol tank, due to a spark in the engine, triggered by the collision.
"The CNG cylinder was intact. The car is now at Palwal police station," he said.
To identify the victims, the police recovered SIM cards from the burnt mobile phones in the car, called some numbers stored in them and reached their family members.
The Bansals' family members reached Palwal to claim the bodies after post-mortem.
