US border police have found a sophisticated drug smugglers' tunnel the length of six football fields linking Southern California with Mexico and arrested two people.

The US Customs and Border Protection agency said the tunnel ran between warehouses in Otay Mesa, California, and Tijuana, Mexico. It measured 1,800 feet (550 meters) and was equipped with a rail system, lighting and ventilation.
