Border patrol discover underground tunnel, 30 illegal aliens

""

More than two dozen illegal aliens were detained at the California-Mexico border in Otay Mesa, California, early Saturday morning, but the discovery of the group also turned up an underground tunnel.

“While subterranean tunnels are not a new occurrence along the California-Mexico border, they are more commonly utilized by transnational criminal organizations to smuggle narcotics,” the U.S. Customs and Border Protection wrote in a news release. “However, as this case demonstrates, law enforcement has also identified instances where such tunnels were used to facilitate human smuggling.”

Authorities say a few of the illegal aliens were spotted after they crossed the border just after 1:00 a.m. Once caught, several tried to turn back and escape back into the tunnel. Altogether, 30 people were detained, 23 of whom are Chinese nationals and the remaining seven are Mexican nationals. The group was made up of 25 men and five women.

The group remains in custody and the investigation ongoing.
