A group of illegal immigrants from South America have been indicted by a federal grand jury for allegedly using construction worker disguises, blowtorches and cell phone jammers, among other “sophisticated tactics,” to defraud banks in several states of more than $4 million to rob federal prosecutors.

The group, made up primarily of Chilean nationals, targeted more than 29 banks and credit unions across California, Oregon and Washington between May and October, U.S. Attorney Phillip A. Talbert announced.

According to court documents, the group located ATMs in “vulnerable locations,” then rented short-term vacation properties nearby and rented used cars on the “black market.”

Officials said nine of the 11 people charged were arrested last week and two others were arrested in Washington on Oct. 30.

In one incident, prosecutors said, the suspected thieves scouted a store next to a Wells Fargo in Modesto, California, broke in at night and cut a hole in the wall to get to the bank's ATMs.

Authorities released images of the suspected bank robbers dressed as construction workers and wearing hard hats, surgical masks and high-visibility vests.

In another incident, prosecutors allege, the bandits attacked a bank in Fall River Mills, California. They allegedly used blowtorches, saws and other power tools to gain access to the bank and its interior safes. The suspected bandits were interrupted and fled, leaving behind some of their tools.

Authorities said they found hundreds of pounds of robbery tools, disguises, fake identification documents and more than $100,000 in cash at several short-term rental properties in Oregon and Washington.
