A motorist noticed something suspicious when he went to use the self-service machine. He was aware of skimming devices, having read a warning on the North Yorkshire Police Facebook page about a similar device earlier this year.
The device, which had been attached to the machine using velcro, came away in his hands. It has now been removed for examination.
Police constable John Armstrong, of York Police said: “The motorist in this case did exactly the right thing, by remaining vigilant, acting on his suspicions and contacting the police. I would urge people to always take extra care when using cash machines and self-service petrol pumps, to avoid falling victim to card skimming devices.”
CCTV enquiries are under way, and anyone with any information about the incident is asked to contact North Yorkshire Police.
