BOGOTA, May 14 (UPI) -- Police in Colombia said they have uncovered two million-dollar submarines in the past two days that were being used by drug cartels to smuggle cocaine into the United States.
The first discovery came when a 45-foot semi-submersible watercraft was spotted off the coast of Candelilla de la Mar, in the south of Colombia near the border with Ecuador.
The vessel was capable of carrying up to four tons of powder drugs, police said, though no drugs were found on board.
The sub had been equipped with a diesel motor, propellers and a rudder, leading police to believe it was near ready to haul a drug shipment north.
A second submarine was found and destroyed in the Timba River, which feeds into the Pacific Ocean. Police said six men were arrested in that incident.
Each vessel was valued at $1 million, police said.
