Major ATM Theft Ring Leader Arrested in Newport Beach

News Summary

Diego Ananias Arellano Diaz, 34, was arrested in Newport Beach for leading a crew responsible for stealing over $4 million from ATMs across several states. This coordinated crime operation, which involved disguises and sophisticated techniques to bypass security, has led to serious charges of bank robbery and conspiracy against him and his accomplices. If convicted, Arellano Diaz faces significant prison time amid ongoing investigations into the extensive criminal network.

Newport Beach, California – Diego Ananias Arellano Diaz, aged 34, was arrested last week in Newport Beach and is facing serious charges of bank robbery and conspiracy to commit bank robbery. The U.S. Attorney’s Office for the Eastern District of California has implicated him as a key figure in a coordinated theft operation targeting ATMs across several western states.

Authorities allege that Arellano Diaz was part of a crew responsible for stealing over $4 million from more than 29 banks and credit unions across California, Oregon, and Washington between May and October 2024. The crew’s criminal activities involved a sophisticated method of operation, including the use of blowtorches and cellphone jammers to bypass ATM security systems, highlighting their planning and determination.

The robbery crew, which disguised themselves as construction workers by wearing hard hats, vests, and surgical masks, targeted ATMs located in what were described as “vulnerable locations.” During the heists, they utilized armed sledgehammers and spray-painted surveillance cameras to conceal their identities and actions. Furthermore, to evade detection, the crew rented short-term vacation homes and used cars acquired through the black market.

History of Criminal Activity

In October 2024, a grand jury charged a total of 11 defendants with bank robbery and conspiracy related to this series of incidents. Arellano Diaz was initially identified only as “John Doe” until investigators discovered a GoPro camera at an Airbnb used by the crew in Welches, Oregon. The camera contained incriminating video footage, allowing law enforcement to establish his identity and link him to the robberies.

In addition to his involvement in the ATM heists, Arellano Diaz is also believed to be connected to a bombing incident at a Target store ATM in San Ramon, California, which occurred on July 20, 2025. Fortunately, the bombing did not result in any injuries. His capture comes after a previous arrest in February 2025 in Los Angeles County for assault with a deadly weapon against a police officer or firefighter; he disappeared shortly after being released on a $75,000 bond.

Legal Repercussions

If convicted of the charges against him, Arellano Diaz faces a maximum sentence of 20 years for bank robbery, along with an additional five years for conspiracy. Law enforcement continues to investigate his activities, along with those of his alleged accomplices, as they work to dismantle the extensive criminal operation that has caused significant disruption across multiple states.

Conclusion

The arrest of Diego Ananias Arellano Diaz marks a significant development in a prolonged investigation into a series of high-stakes robberies that tested the capabilities of law enforcement agencies across the West Coast. As the case unfolds, authorities will ensure that justice is served for the victims affected by these brazen and calculated crimes.
