At the beginning of April 2021, a large-scale operation against massive fraud with fuel taxes resulted in the arrests of 23 suspects and in the seizure of assets worth €600 million. Investigations conducted by Italian authorities in cooperation with authorities from Bulgaria, Germany, Hungary, Malta, and Romania and supported by Eurojust helped dismantle two mafia-style organised crime groups (OCGs) from Naples and the Reggio Calabria. They had been running a fraud scheme with fuel tax worth almost €1 billion. Judicial authorities were able to make use of the new Regulation (EU) 2018/1805 on mutual recognition of freezing orders and confiscation orders, which entered into force in December 2020 (→ eucrim 4/2020, 288).
