Businesses in the Highlands and Islands are urged to be on their guard.
The police have issued a warning following reports of a telephone scam involving people claiming to represent the force.
The attempted fraud involved a business in the Highlands being contacted by an individual claiming to represent Police Scotland seeking advertising sponsorship in relation to an upcoming road safety campaign.
The business which had been contacted terminated the call and contacted Police Scotland on 101 to establish whether the contact was genuine or not.
No money was handed over.
Police Scotland is now urging other businesses to be vigilant against such an approach and offer reassurance that in no circumstances would such contact be made using a "cold calling" approach.
Anyone who receives a similar call should end the contact and then phone Police Scotland on 101 to verify the call and report any concerns.
Enquiries are ongoing into the recent incident and any further information can be passed to officers by calling 101, quoting reference NN27485/17, or call Crimestoppers on 0800 555 111.
