GANG members behind a spate of ATM thefts are waiting until machines have been filled full of cash before targeting machines, netting hundreds of thousands of pounds in the 'smash and grab' raids.
With some rural cash machines holding up to £120,000, police believe that more than one gang may now be operating with members staking out targets to monitor times when they are stocked with cash.
However as steps are being taken to try to thwart raids, industry insiders say that dye packs used in the past to reduce cash-in-transit robberies, are no longer effective due to the recent introduction of Polymer banknotes.
Dye packs which explode and damage paper notes, rendering them unusable, have already been fitted in some bank machines, however the dye does not stick to the new style banknotes.
Analysis: Slow response from PSNI doing nothing for confidence in policing
The owner of a Co Derry Centra store targeted in the latest attack, Martin O'Kane, has said he "probably won't get another cash machine in again, and that will be the local community losing out."
Other rural businesses are considering removing their ATM machines rather than risk being targeted.

Footage of the latest attack shows a digger driving through a security gate then tearing the ATM machine from the wall of the Centra store, just outside Dungiven at about 4.30am on Sunday.
In a pattern similar to previous raids a digger was stolen from a nearby building site prior to the attack.
The cash machine was lifted into a Citroen Berlingo car which had part of its roof cut off. Masked men are seen in CCTV footage of the smash and grab which took just over four minutes from start to finish.
Afterwards the car was driven away with the cash machine sticking out of the roof.
It is the latest in a series of cash machine thefts on both sides of the border. The PSNI has said it is the eighth such incident in Northern Ireland in 2019, with more than a dozen similar attacks since the current spate started last October.
Last week, there were two separate incidents of cash machine thefts - one outside a shop in Co Antrim and the the wall of a bank in Co Monaghan.
Despite a specialist task force being set up to investigate the raids there has been just one arrest and no charges in relation to the robberies.
Ron Delnevo, director of the ATM Industry Association, called on the public to help. "What we need to do to stop these robberies is address how they are getting these vehicles and make sure we are alert to the fact that these vehicles are sometimes moving about at unusual times, and alert the authorities when we see that happen".
