During the Joint Action Day “Arktos 3” carried out in June 2021, law enforcement authorities in seven EU Member States succeeded in seizing more than 6.7 million cigarettes, and 2.6 tonnes of raw tobacco, along with half a tonne of illegal drugs. 15 smugglers were arrested and more than 220 fraudulent documents detected. Operation Arktos targeted criminal activities at the EU’s northeastern land border, which is a popular route for smuggling goods into the EU. The operation was led by Frontex and assisted by OLAF, Europol, Eurojust, and Interpol. OLAF supported mainly by exchanging information between EU Member States and customs authorities. The operation was coordinated under the umbrella of the European Multidisciplinary Platform against Criminal Threats (EMPACT), a four-year plan for the fight against serious and organised crime (→ eucrim 2/2021, 89-90 and eucrim 2/2020, 114). It was the third time that operation Arktos was carried out. It focuses on detecting excise goods smuggling via EU external borders (→ eucrim 4/2020, 278).
