Residents in Lancashire are being conned out of money with fake letters demanding a fine for dog fouling.
The letters said an anonymous source reported the residents
The letters, claiming to be from Lancashire County Council, have been circulated in the Wyre area.
They ask the addressee to settle a fine for their pet fouling the pavement, after notification of the offence by an "anonymous source".
Wyre and Lancashire County Councils joined forces and have urged anyone who gets the letter to contact them.
Wyre Council said it had the power to issue dog fouling fines, but they were usually on-the-spot.
The letter stated that a non-existent "Environmental Services Department" has carried out an investigation.
It said that the maximum penalty for the offence was £1,500 but that the recipient would only have to pay a penalty of £100 plus £25 costs.
Paul Noone, Lancashire County Council trading standards officer, said: "We are making people aware of these fake letters as they are nothing more than a scam.
"Lancashire County Council does not issue this sort of fine and, although the letter looks genuine at first glance, it is quite clearly not from us.
"We do not yet know how many of these letters have been sent out, but we need to make people aware just one fake letter can lead to people being conned."
