Prosecutors from DIICOT arrested a former commercial director of Oil Terminal after raids tied to alleged petrol contraband through the Port of Constanta. Investigators say the network operated in Romania and involved a scheme to evade VAT and excise duties, with prosecutors estimating damage in the tens of millions of euros. They allege that more than 66,000 tonnes of diesel were taken out and sold illegally via Port of Constanta using companies based in Malta and Switzerland. Police carried out wide-ranging searches in Bucuresti and several counties, including Constanta, Bacău, Prahova, Galați and Ilfov. In total, 46 raids were conducted. The case targets an alleged organised criminal group, accused of VAT and excise tax evasion, obtaining money illegally, fraud, bid rigging-related offences and abuse of office. Prosecutors say the group was set up in 2023, then expanded with additional members. According to investigators, the alleged method involved inserting an insolvent company into the transaction chain. They say it issued invoices for diesel deliveries that did not take place, and that the receiving firms used those invoices to unlawfully deduct VAT. Between December 2023 and August 2025, investigators cite more than 340 such invoices worth more than 208 million lei, with an estimated VAT prejudice of about 33.3 million lei. DIICOT said that, based on evidence obtained so far, it has not resulted that the excisable product, diesel, came from distributors located in the Russian Federation. DIICOT said the case focuses on tax obligation evasion, namely payment of VAT and excise. Investigators also allege schemes involving incorrect reporting of fuel quantities and cases where payments were reportedly shown as made using documents linked to other firms. Prosecutors estimate losses from these parts of the case at millions of lei. On top of the tax matters, investigators allege that through seven firms the suspects obtained over 41 million lei in state-guaranteed financing using false or incomplete documents about investments, own contributions and repayment sources, with additional alleged fraudulent commercial credits. The investigation is ongoing, with the former Oil Terminal commercial director held following the DIICOT arrest after hours of hearings.
