BOGOTA, Colombia – Colombian officials say tests reveal a seized shipment of asphalt turned out to be expertly disguised cocaine.
Gen. Ricardo Restrepo said in a press conference Saturday that officials are still trying to determine how the cocaine was mixed with the asphalt. He said the process required "very expert" knowledge.
Police last month seized the shipment of 12 sacks of what appeared to be asphalt on a road leading to the city of Maicao some 480 miles (770 kilometers) northeast of the capital of Bogota.
The first tests failed to determine what the material was, but subsequent tests determined the small black rocks in the shipment were nearly 700 pounds (316 kilograms) of cocaine.
Colombian authorities have in the past found cocaine hidden in creative ways, including mixed with coffee and stashed inside lemons and bananas.
