U.S. law enforcement discovered a massive drug smuggling tunnel — the length of six football fields — running under the U.S.-Mexico border on Friday.
The sophisticated passageway connected Tijuana, Mexico with a warehouse in San Diego, and included a railway, ventilation systems, electricity and reinforced walls, according to authorities. The tunnel ran 1,744 feet, around a third of a mile, and was 61 feet deep, about six storeys.
Law enforcement is unsure of how long the tunnel was operating but seized almost 2,000 pounds of cocaine, 165 pounds of meth and 3.5 pounds of heroin in connection with the investigation, valued at around US$25 million.
