Authorities find drug-smuggler’s tunnel under the U.S. and Mexico border

Anti-drug agents have found a smugglers’ tunnel including a rail track, electricity and ventilation system

A drug-smuggler’s tunnel has been unearthed under the U.S. and Mexican border.

It led from the Mexican city of Tijuana to a warehouse located 300 feet from the San Diego border.

Six people have been arrested for their alleged involvement in the scheme.

They are accused of conspiring to distribute cocaine, heroin and methamphetamine, among other crimes.

“There is no more light at the end of this narco-tunnel,” says the U.S. Attorney Randy Grossman.

The tunnel is believed to be over 1,750 feet long, and was fitted out reinforced walls.

Close to 100 tunnels have been found in the same area, but this was one of the largest.
