U.S. Border Patrol agents have found a suspected drug tunnel with lighting and a rail-car system that connected to a home across the border in Tijuana, Mexico.
Immigration and Customs Enforcement spokeswoman Lauren Mack said agents patrolling west of the San Ysidro port of entry Tuesday morning found a sinkhole close to the U.S. border fence that opened up into the tunnel.
Mack says the tunnel was about 220 yards in length, had a cart inside and the walls shored up. But it was still under construction, so an exit on the U.S. side had not been constructed.
Macks says no drugs were found, and no arrests have been made.
More than 100 miles away in Calexico, border patrol agents discovered a border tunnel there.
On Saturday, agents arrested a man at the border they say was trying to smuggle 69 pounds of methamphetamine. When officers were investigating Monday, they found a four-by-four tunnel with lighting and ventilation running from a house in Mexico to the U.S. approximately 230 feet in length.
Drug cartels have increasingly turned to tunnels to smuggle their loads into the United States. More than 75 tunnels have been discovered along the border since 2008.
