SAN DIEGO - Authorities discover what they're calling a 'fully operational' drug tunnel under the border. The tunnel was discovered by police and members of the Mexican National Guard at a home in Tijuana Saturday night, and the exit point is in a warehouse on the U.S. side in Otay Mesa.
Authorities in Tijuana say the tunnel was used to smuggle drugs and for other illicit activity. The Border Patrol has sealed up the tunnel on the U.S. side and is investigating the incident. This is the 90th cross-border tunnel found in San Diego County since 2009.
