SAN DIEGO — A nearly half-mile-long tunnel leading from Mexico to San Diego was discovered and more than a ton of cocaine and seven tons of marijuana was seized, the U.S. attorney’s office said Wednesday. Six people were arrested.

The tunnel extends 300 yards from a house in Tijuana, Mexico, to the border and then 500 yards on the U.S. side to a fenced lot in a San Diego industrial area. The tunnel was equipped with a rail system, ventilation, lights and a large elevator, officials said. The exit on the U.S. side is about 3 feet wide and was covered by a trash bin. The six people arrested in San Diego on Friday were charged with crimes involving drugs and construction of the tunnel.(Nypost.com)…[+]
