A criminal network responsible for smuggling oil in India has been broken up after a police investigation.
Officials claim the accused used water tankers to steal millions of litres of crude oil in Rajasthan.
The investigation centres on the Cairn India oilfield in Barmer district and 25 people have been arrested.
It is believed fifty million litres of oil were stolen over a six-year period and sold to two local factories.
Local news sources report that tankers were used to take waste water from the oilfield. But those involved in the theft were filling two of the five compartments in each tanker with crude.
Estimates suggest the crude taken could be worth more than $7m (£5.3m).
