The police raid on an unauthorised motor garage in Burmamines in June

Two months after busting a diesel adulteration racket, the police are unable to book the alleged culprits as test reports from Indian Oil Corporation are inconclusive.

Anil Kumar Ray, the special officer (rationing) of East Singhbhum, said they had seized samples of fuel and chemicals from an abandoned factory in the Burmamines area on June 4 and sent them for testing to two labs.

While the IOCL report was ambiguous, reports hadn’t yet come in from Calcutta-based Central Laboratory.

“We have got the test report from the IOCL lab and handed it over to a first class judicial magistrate for necessary action in the case which was registered at the Burmamines police station on June 6,” Ray told The Telegraph.

Superintendent of police (City) Kartik S pointed out that the IOCL test report was ambiguous.

”We have, therefore, asked IOCL — through the special officer — to get the samples re-tested for a conclusive result. We are depending on the IOCL lab report as the test report from the Calcutta lab is likely to be delayed,” he said.

An FIR lodged by Rajendra Prasad Mahto, a marketing officer in the food and civil supplies department, on July 6 names Jamshedpur businessman Ashok Vig, his son and a business manager.

That was two days after the district police seized three tankers loaded with kerosene and diesel, chemicals and several tubes and pipes apparently used to transfer fuel from the vessels.

Sources claimed that after questioning Vig, who owns a petrol pump in the area and several oil tankers, the police were fairly certain that the factory premises was being used to adulterate diesel using the kerosene and the chemicals they seized.

But Vig and the others named in the FIR have been absconding ever since the case was registered on July 6, said officer-in-charge of Burmamines police station Nand Kishore Prasad.

“In 2010, a case of petrol adulteration was registered against Ashok Vig. It is still pending in the court,” said city SP Kartik, but refused to divulge further details of the ongoing probe.
