Suspected Traffickers From Serbia, Montenegro Arrested

Serbia's intelligence agency BIA announced that it cooperated in the operation with the Spanish police.

The drugs were transported from Argentina aboard a ship, and were intercepted in the port of Tarragona.

Jovan Stojic, chief of the BIA director's office, told B92 in Belgrade on Thursday that the agency had no information that would indicate the six were part of a larger organised crime group.

"Our intelligence shows they acted autonomously," he said.

Stojic named the suspects as Serbian citizens Drazen Krasic, Dalibor Dramicanin and Goran Crnomarkovic, and Montenegrins Nikola Mrvaljevic, Vuk Popovic and Ilija Brankovic.
