Belgian authorities announced on Monday that they had seized 27.64 tons of cocaine with a street value of 1.4 billion euros ($1.7 billion) in the industrial port of Antwerp over the past two months, with a record 11 tons discovered Friday night alone. In addition, an employee of a port company and an employee of the city of Antwerp have also been arrested.

Authorities attributed the seizures to the alleged decryption of half a billion messages sent using Sky ECC—a now shut down encrypted phone company and network popular among drug traffickers—in early March. Belgian and Dutch authorities pointed to the decrypted messages as the catalyst for the subsequent arrests of 48 people in Belgium and 73 in the Netherlands supposedly connected to the drug trade.
