U.S. Customs and Border Protection officers came across 128 illegal immigrants on Friday after they had presumably been abandoned by smugglers.
The large caravan of people was noticed near the Lukeville Port of Entry.
“Transnational criminal organizations exploit the vulnerability of foreign nationals with false promises of legal status and encourage dangerous crossing methods, placing their safety at risk,” the agency said in a statement.
The apprehended migrants were from El Salvador, Guatemala, Honduras and Mexico, meaning some of them had to cross as much as 2,500 miles before reaching the U.S.
The detainees included families, including children as young as age 4. Some also had previous immigration violations. The whole caravan is set for deportation from the U.S.
