Cases of cash machine fraud, where a device is used to trap money inside the ATM machine, have increased more than 15-fold in London in the past three months. Reported incidents have risen from 150 across the UK in May, to 2,500 in London alone in August, according to figures from Link and London's Dedicated Cheque and Plastic Crime Unit (DCPCU).
Criminals insert a device called a cash claw behind the guard on the cash drawer of an ATM. The device is undetectable to the public, who use the machine as normal until their cash fails to eject.
"The machine goes out of service and then the criminal comes along, forces open the drawer using a pair of pliers or a screwdriver, forces the device out of the cash machine, bringing the customer's money with it," explains Detective Chief Inspector Dave Carter, head of the DCPCU.
Customers are advised to immediately report any banknotes undelivered from cash machines.
