Elaborate tunnel used to smuggle drugs to US

A tunnel designed to smuggle drugs from Tijuana, Mexico, to San Diego was equipped with lighting, ventilation, and an electric rail system, US authorities said, making it one of the most sophisticated secret passages discovered along the US-Mexico border.

Authorities seized eight- and-a-half tonnes of marijuana and 327 pounds of cocaine in connection with the tunnel’s discovery, according to court records. Three men, who authorities say worked as drivers, were charged on Thursday with possession of cannabis and cocaine with intent to distribute. US attorney Laura Duffy said they face prison sentences between 10 years and life if convicted.

The tunnel, which zigzags the length of nearly six football fields, links warehouses in Tijuana and San Diego’s Otay Mesa industrial area. The area is filled with nondescript warehouses, making it easier to conceal trucks being loaded with drugs.
