A tunnel running more than seven tenths of a mile was discovered Wednesday night connecting Tijuana, Mexico and Otay Mesa, California. The tunnel was found by the US Drug Enforcement Agency (DEA) and Immigrations and Customs Enforcement (ICE) and is the longest found to date. It is said to be 5 feet high and 3 1/2 feet wide. Inside the tunnel they discovered 2 tons of Marijuana. No doubt it was also used for illegal aliens.

Since 9/11 more than 20 tunnels have been discovered in Arizona and California.

Authorities said they believe the passageway originates under a warehouse about 150 yards south of the border and surfaces about a half-mile north of the border in another warehouse.

They "believe"? What they haven't investigated it or the Mexican government won't allow them to?

Made of concrete, the passageway had lighting, electricity, ventilation and a pump to remove water, said Lauren Mack, a spokeswoman for Immigration and Customs Enforcement.

"It's definitely expected to be related to a major drug cartel in Mexico," she said. No arrests have been made.

An investigation is under way to determine who built the passageway.

"We've now got a dedicated tunnel task force, which works with the DEA and border patrol to proactively look for tunnels," Mack said.

Well that's good to hear. It would have been nice if they would have already had a team though since this seems to be a common thing these days.

The article notes that this particular tunnel was discovered by information from an informant and ground penetrating radar.
