Nogales, Mexico — Mexican federal forces have shut down the longest drug smuggling tunnel, located on the Southwest border between the U.S. and Mexico.
The tunnel was uncovered following a joint investigation by the DEA and Nogales Border Patrol with Mexican authorities.
They found that the tunnel ran below ground from Nogales, Mexico, to another house in Nogales, Arizona.
U.S. officials reported that the 48 one foot long tunnel was shored up with wood, connected with electric lighting and fitted with fans to circulate air inside.
They added that agents arrested three men and seized more than 640 pounds of marijuana and heroin while securing the tunnel.
According to U.S. Federal officials, more than 75 cross border tunnels have been discovered on the Southwest border between the United States and Mexico since 2008.
