Authorities have found about 50 to 60 pounds of marijuana they believe smugglers tried to get into Arizona via a sewer pipe that runs through the U.S. and Mexico.

The four bundles caused the sewer line to back up and spill into a Nogales, Arizona, home. They believe smugglers sent the drugs through the sewer in Mexico and that someone in the U.S. side caught them by approaching the sewer through an illegal tunnel under the house.

City Manager Shane Dille says city officials discovered waste coming out of the house on Sunday.

The spill destroyed the house near the border and affected two businesses nearby. Dille says the city has been cleaning the area and on Tuesday night discovered the bundles of marijuana in the sewage line.
