TUCSON - Authorities in Nogales discovered a cross-border tunnel that was being used to smuggle marijuana into the U.S. from Mexico, officials said.
The tunnel was found after Nogales police officers noticed a strong odor of marijuana coming from a house near a border crossing on Tuesday, Santa Cruz County Sheriff Tony Estrada said.
No one was home when officers knocked on the door, so they called a special sheriff's anti-drug task force, which obtained a search warrant, Estrada said.
Authorities found 110 bundles of marijuana in the house and a tunnel entrance hidden behind a stove, Estrada said. The tunnel led to a nearby wash in Mexico, and more marijuana was found in a tunnel storage room.
U.S. authorities seized 1,390 pounds of marijuana in all, Estrada said.
Mexican authorities were notified, and they found more marijuana, some crude digging instruments and a wheelbarrow on that side of the border, Estrada said.
Several cross-border drug smuggling tunnels have been discovered in Nogales this year.
