ILLEGAL signs attempting to trick residents into paying hefty fines for parking have been sprouting up across St Helens.
The poorly designed posters have been left on lampposts throughout the borough.
They warn that from April 2 anyone caught parking on public pathways could be fined £500 and receive three penalty points.
Town hall officials believe similar scams have been operated in other parts of the region.
In those cases, bogus enforcement officers make follow-up calls demanding payment.
The posters include a St Helens Council logo which the scammers are likely to have downloaded from the internet.
A council spokeswoman said they had no information to suggest any local people had fallen for the scam.
If anyone is approached they are advised not to let them in and do not pay any money. The incident should be reported to the council on 01744 676789 or Merseyside Police on 0151 709 6010.
