Some more instances of attempted A-T-M jackpotting at some area banks have led to the arrest of four men.
A-T-M jackpotting is when someone attempts to access the inside of an A-T-M to get it to give large amounts of cash by installing malware to access the computer components.
Authorities say a group of four Chicago men were arrested in Earlville on Sunday after an investigation into A-T-M’s being tampered with in Farley and Dyersville on Saturday
