Cash machine users are being warned to be careful after a cloning device was found on one in part of Leicestershire.
Police said it was difficult to know how long it had been in place
Officers found the device on a machine on Atkins Way in Burbage after being alerted by a member of the public.
The device consisted of a card reader, which copies the details of the card, and a camera to record the pin.
Police said that anyone who had used the cash machine in the past weeks should contact their bank and consider cancelling their card.
PC Lesley Clarke said they could not be sure how long the device had been attached but that there could have been some tell-tale signs.
"It may have been that the people responsible were parked or sitting close by and downloading the data as people were using the machine," she said.
"We'd therefore be keen to speak to anyone who saw people in the vicinity behaving oddly, perhaps sitting in a vehicle within sight of the machine."
