A drug-smuggling tunnel and approximately 30 tons of marijuana were discovered early Wednesday in the Otay Mesa section of San Diego, said officials from Immigration and Customs Enforcement and the United States Drug Enforcement Administration.
The officials said the tunnel, which contained much of the drugs, was roughly 600 yards long and had been used to shuttle marijuana between California and Tijuana, Mexico, for some time.
exican officials said they found five tons of marijuana at the southern end of the tunnel. The discovery comes weeks after Mexican authorities seized 134 tons of marijuana in Tijuana, a record-breaking amount for the country. Officials said it was unclear whether the tunnel discovered Wednesday was related.
In the last four years, authorities have found more than 75 such tunnels along the border.
