A new cross-border drug tunnel has been discovered under the Otay Mesa Border Crossing, south of San Diego, authorities confirmed to NBC San Diego.
The tunnel marks the third such discovery in Southern California in the past month.
U.S. Customs and Border Protection (CBP) officers referred inquiries to the U.S. Attorney's office. U.S. Attorney Laura Duffy's office confirmed a cross-border tunnel has been discovered, but would only reveal the details Wednesday at a news conference.
Authorities swarmed a facility on Marconi Drive Tuesday afternoon starting at 2:15 p.m. The building is located approximately 1,000 feet from the U.S.-Mexico border.
The tunnel marks the third similar discovery in recent weeks.
Officials found a 142-foot long cross-border tunnel east of Calexico during a routine patrol of the border. Depression in the soil exposed an 18-inch hole, where the agent found lumber and electrical wiring that indicated it was an operational tunnel.
A month ago, authorities found a secret, cross-border tunnel hidden in a home built specifically for the purpose of concealing the tunnel's entrance. Officials said they believed it was the first instance in California where smugglers built a home for the sole purpose of transporting drugs.
No other information was immediately available.
