Police could not lay hands on the culprits though they were informed of the abduction within an hour.

Chawla was kidnapped by Kunal Bhandari alias Rocky, 27, Rishabh Chauhan, 24, Sukhwinder Singh alias Manni, 22, and Gaurav, 20, around 2.30 p.m. Tuesday.

Police were informed at 3.17 p.m. and the accused started making ransom calls to Sanjay Chawla around 5.45 p.m. and made several such calls thereafter.

The accused took Ribhu in their Wagon R Car and roamed for several hours in Delhi and Haryana when police had got the car's registration number.

'They were on roads and hardly had any stopover. They just stopped to buy snacks and drink for the deceased. The number which we were given was fake as the accused had twice changed it. They changed it before and after the abduction,' Kashyap said.

'And without any specific information, no car can be stopped,' he said.

In general practice, whenever such information is passed to the police control rooms, barricades are erected for checking across the capital and suspected cars are stopped for checking and the occupants are asked to verify their identities.

Police did not know when the Wagon R car left and re-entered the capital.
