Colombian police found a homemade submarine capable of carrying $200 million worth of cocaine on a Pacific Ocean smuggling mission, police said on Friday. Police, who acted on a tip, made no arrests after finding the submarine hidden in the port of Tumaco, near the border with Ecuador, the Administrative Security Department detective force said. It was the second publicized case of Colombian drug smugglers trying to use submarines. In 2000, another underwater vessel was found far from the coast in the Andean mountain capital, Bogota. "They started building the submarine about six months ago, using small pieces so as not to make people suspicious. They wanted to have it ready for Easter because they thought the police would drop their guard," said Eduardo Fernandez, head of the DAS in the southern province of Valle del Cauca. --More 2214 Local Time 1914 GMT
