PRAGUE (Reuters) - Czech police said on Wednesday they had seized a 135 kg (300 lbs) cache of cocaine in the central town of Melnik in a raid coordinated with German and U.S. anti-drug squads. The cocaine, the largest amount ever seized in the Czech Republic, was hidden in a shipment of dried bananas from South America, police said in a statement. Police said the estimated 1,400,000 doses had a street value of nearly half a billion crowns ($14.2 million). An unnamed 45-year old man was detained in the Melnik raid and three others were arrested simultaneously in South America, Czech police said, but they declined to specify where the shipment originated or in which country the three were detained. The raid was carried out in mid March but only announced on Wednesday. Drug usage and trafficking has multiplied in the Czech Republic since it opened its borders after the fall of Communism nearly 10 years ago.
