Officials tell Eyewitness News five to eight people broke in through a window in the cafeteria of the Willowbrook location.
They grabbed the ATM and began carrying it out of the building, until a security guard making his rounds saw them.
The thieves dropped the ATM and took off in two vehicles.
Police are checking surveillance video to see if cameras caught a better look at the thieves or the vehicles.
