Mexican authorities have unearthed a 32-foot-long smuggling tunnel at the Arizona border.

It was the third one in the area that officials have found in less than a month, according to the Arizona Republic.

The latest tunnel was uncovered across the border from Nogales, Ariz., according to a Wednesday tweet from the Mexican Federal Police.

It was used “for the transfer of drugs and people,” officials said.

The tunnel had a circular door just big enough to fit a body, police video shows.

Since December, Mexican officials have uncovered a 50-foot and a 65-foot tunnel in the same area.
