We are urging businesses to be aware of how to spot suspected counterfeit bank notes during the festive period.
Several reports have been received across the Highlands & Islands relating to the use of fake currency and officers are keen to encourage people to be aware of the warning signs.
Officers from the divisional Preventions and Interventions Unit have been visiting businesses across the region this week in the build-up to Black Friday and the festive period offering advice about retail crime.
Constable Keri Jones from the unit said: "We have been asking retail workers who regularly handle cash to be on their guard so they are able to spot the warning signs relating to counterfeit money.
"Our message is simple - please thoroughly check all bank notes, particularly if they are of high value and being used to purchase a low cost item, before completing a transaction.
"Please examine the notes carefully for texture, watermark, sharpness of print and size.
"Retailers can take simple steps to avoid being scammed in this fashion by using such items as counterfeit note detector pens or UV scanners, both of which greatly increase the chances of picking up a counterfeit note before change has been passed of goods supplied.
"A number of resources are available online from banks which issue notes giving advice on how to spot fakes and we recommend that anyone handling cash makes use of these.
"Anyone who deliberately uses counterfeit currency is committing a crime and we will investigate all instances reported to us."
Anyone who has concerns about counterfeit money should call police on 101 or Crimestoppers on 0800 555 111.
