GREENFIELD — More than $100,000 was stolen from the “ATM Tree” in the Big Y plaza early Friday morning in a robbery that Police Chief Todd Dodge said was likely not performed by amateurs.

“We can expect at this point that the individuals who were responsible for this clearly knew what they were doing,” Dodge said in a phone interview on Monday. “They were in and out within minutes and they got away with a significant amount of money. They stole a car in town, which was the truck used to pull the front off of this ATM, and it looks like the people involved have traveled all over the eastern seaboard, including by air.”

Local police responded within minutes of receiving reports that the ATM’s alarm went off at approximately 3:03 a.m. on Friday. Upon arrival, Dodge said officers saw a large Ford pickup truck with its engine running next to the ATM. The machine’s front end had been pulled off, exposing the area where cash had been stored only days before. No one was inside the truck when police arrived.

“A large Ford pickup pulled up to the ATM, hooked up a chain to the front and ripped the front off, exposing the cash cartridges, and they made away with all the money in there,” Dodge said. “One of the chains they used to hook to the ATM to pull the door off actually got wrapped around a pole, so the truck actually got stuck. So when they arrived, they found the truck doors open, running, but unoccupied and the money and suspects gone.”

Dodge said a Spruce Street resident had reported the truck missing only hours before the robbery. He said that while reviewing security camera footage, State Police investigators discovered a second vehicle involved in the robbery, which had been previously rented out of Texas and later abandoned at Boston Logan International Airport.

“It seems like a second vehicle arrived shortly after that truck got stuck and they were seen running from it. A second vehicle pulls up on Mohawk Trail and it appears these individuals got in it and they [fled],” Dodge said.

Given the level of planning that appears to have gone into the robbery, Dodge said he expects the robbery will prompt a “tricky” and “comprehensive” investigation involving many agencies across jurisdictions.

As of 5 p.m. on Monday, Dodge said police had begun to identify potential suspects in the case.

“It seems like these individuals knew what they were doing. This was obviously well planned at this point in time,” Dodge said. “Individuals are starting to be identified, although we’re not completely sure of their level of involvement in this.”

Bank President Thomas Meshako said Greenfield Savings Bank has received “quite a few” phone calls from customers complaining about the non-functioning machine and said the issue is not the result of neglect. The ATM itself was smashed and the tree structure was damaged.

“That tree is iconic to the area,” Meshako said. “It’s just a shame that this happened.”

The bank president said he is unsure how long the ATM will be out of commission, as the bank is working with its insurance company. Customers can always use the ATM at the Greenfield Applebee’s Grill + Bar at 141 Mohawk Trail.

The 25-foot-tall ATM was designed by artist Thor Holbek and opened in 2008. An overhanging fake mushroom shelters vehicles at the kiosk. The sculpture was recently paid a visit by a New York Mycological Society member who posted photos on Facebook. Mycology is the study of fungi.
