Police in Cheshire say they have received several reports of distraction thefts targeting supermarket shoppers.
Officers say offenders tend to target older people who are shopping in the supermarket, watching them enter their number into the chip and pin device at the checkout, then one person will distract them when they've put their bags in the car while another steals the victim’s bank card from their purse.
The offenders will then empty the victim’s account of cash either at cash machines or by going on a spending spree.
DCI Paul Beauchamp said: "Of concern to us is the fact that these thieves appear to target older shoppers when committing their crimes.
"We are again taking the opportunity to remind the public to be on their guard and to have an awareness of this type of crime and following simple crime prevention steps.
"Similarly, we want you to always check your bank statements for any inaccuracies or discrepancies, as credit card fraud may not be immediately apparent."
Anyone who sees suspicious activity or had any information should contact Cheshire Police on 101.
