Border Patrol agents in Arizona arrested 10 drug mules Thursday after finding around 40 pounds of marijuana in each person's backpack, according to a Customs and Border Protection statement issued Friday.

Wellton Station Border Patrol agents tracked the group Thursday morning as they smuggled the marijuana from Mexico into the U.S. near Gila Bend, Ariz.

The 10 Latino males appear to be teenagers and were later confirmed to be illegal immigrants. Each male wore camouflage jackets and may have been hired by a drug cartel to carry the pot into the U.S.

Border Patrol seized 390 pounds of marijuana, which is worth an estimated $135,000 on the street — nearly half of what the Customs and Border Protection agency caught on a typical day in 2016.
