Rio De Janeiro: Brazilian police has said they had dismantled a massive drug cartel with operations in 30 countries and sales of at least USD 2.3 million a week. Federal police in the central state of Goias Friday said they had issued 85 arrest warrants, seized 46 buildings worth an estimated 80 million reals (USD 36 million) and frozen several suspects` bank accounts after a 2.5-year investigation. Police did not say how many arrests had been made, but the group`s suspected leader was still at large. The cartel shipped drugs across the Americas and to Europe, Africa, the Middle East and Asia. It had been working on building a submarine and creating an airline to transport the narcotics, according to police.
