A joint national sting between Mexican and U.S. federal agents captured a group of spies who were helping drug smugglers and human traffickers cross the border.

The four-day operation concluded last week and led to the arrest of 19 'punteros' or 'halcones', a Spanish term for spies, who made a hideout in a mountainous region in northwestern Mexican state of Sonora.

According to a statement from the U.S. Customs and Border Protection [CBP], six of the suspects were Honduran nationals with ties to criminal organizations.

The investigation also uncovered 250 pounds of drugs, long-range weapons and tactical communication systems.

The CBP said the drugs from the harvest were being ferried across the border by the same criminal network that had set up the camp site.

'Bi-national collaboration is crucial in ensuring the safety for communities on both side of the border,' said Roy Villareal, Tucson Sector Chief Patrol Agent.

In April, CBP agents busted nine Mexicans with alleged ties to cartel that operated along a neighboring area between Mexico and Arizona.

The group spied for a criminal organization and provided surveillance of border officials near Camp Grip with high-tech gadgets such as solar panels, radios, telescopes and high-range binoculars.
