Police in Spain have arrested 30 people for fuel fraud totalling 120 million euros.
Suspects in 15 Spanish provinces are being detained for a scam which involved buying fuel without paying VAT taxes, then selling it on to customers at a price lower than their legal competitors.
The illegal operation took place in a number of countries including Germany, Britain and Belgium.
Commander Antonio Balas from the Chief Economic Crime ONIF unit said the gang were so sophisticated they had used their own tankers for transporting the fuel.
Fifty-five million euros worth of assets, including top of the range cars, properties and cash, have been seized after police raided 23 properties.
