BERLIN: Germany and Belgium have seized 23 tonnes of cocaine in a record haul of the drug in Europe, German customs said Wednesday.

“The enormous amount of cocaine would have brought in several billion euros (dollars) in street sales,” the customs office said in a statement. German officers had discovered 16 tonnes of cocaine hidden in containers from Paraguay at the port of Hamburg on February 12.

Joint investigations into the stash with Dutch officers led authorities to swoop on another 7.2 tonnes in cocaine at the port of Antwerp in Belgium, German customs said. Dutch police said they arrested a 28-year-old man early Wednesday in the Netherlands in connection with both hauls totalling 23 tonnes.

Investigators also searched two premises — one in Rotterdam and another in a nearby village.

Dutch police said the illicit cargo intercepted was all bound for “the same destination in the Netherlands”. “The seized mega shipments to the Netherlands together form an absolute record. Never before has so much cocaine been intercepted at once,” they said in a statement.

Customs officers at the busy port in Hamburg had decided to take a closer look at the Paraguayan containers after noticing “clear irregularities” with its contents — tin cans that were meant to be filled with putty.
