Businesses are being warned about a telephone scam currently doing the rounds.
The caller introduces himself as Daniel from the Matlock Police and he proceeds by thanking businesses for their support.
He then goes on to offer free gifts and tries to sell advertising space in the police magazines for £299.
A police spokesman said: “The police have a policy of not seeking or providing commercial endorsement of any kind, and do not directly sell advertising space or employ another agency to do so on their behalf.”
Anyone who receives a call of this nature is advised to obtain as much detail as possible about the caller and contact Derbyshire Police on 0345 123 3333.
