Over the pulsating beat at an exclusive nightclub, the arms smuggler made his pitch to a client: 2.5 million euros for enough radioactive cesium to contaminate several city blocks.
It was earlier this year, and the two men were plotting their deal at an unlikely spot: the terrace of Cocos Prive, a dance club and sushi bar in Chisinau, the capital of Moldova.
"You can make a dirty bomb, which would be perfect for the Islamic State," the smuggler said. "If you have a connection with them, the business will go smoothly."
But the smuggler, Valentin Grossu, wasn't sure the client was for real — and he was right to worry. The client was an informant, and it took some 20 meetings to persuade Grossu that he was an authentic Islamic State representative. Eventually, the two men exchanged cash for a sample in a sting operation that landed Grossu in jail.
