Four containers travelling through Malta from Syria to Libya were flagged as potential high-risk containers by the Customs Container Monitoring Unit after risk analysis.[1] Three were declared as carrying crockery detergent and the fourth as carrying blow-torches.[1] Scanned twice at Malta Freeport on Monday 17 September 2018, they showed images that were not homogenous.[1][2]

Customs officers opened them and found bundles of a brown substance hidden inside the detergent; a narcotics field test confirmed cannabis resin.[1] The four containers held 11 tonnes of resin with a street value of €28.5 million.[1][2] Malta Customs called it the largest drug seizure ever made by the Maltese authorities.[2] A week later the European Anti-Fraud Office published Malta Customs’ final figures on the bust.[3]
