Police and trading standards in Denbighshire doorstep crime patrol
Police and trading standards officials in Denbighshire are launching joint patrols in marked vehicles to clampdown on rogue traders committing doorstep crimes.
Denbighshire Trading Standards said the campaign was to warn such people their activities "will not be tolerated".
It comes after a pensioner in Prestatyn was conned out of £120 by paying in advance for some gardening work.
The doorstep caller vanished after receiving the cash.
North Wales Police say officers will carry out high visibility patrols in Prestatyn as part of the investigation.
Sgt Tony Latham said: "Joint high profile patrols will send out a clear message that we are working together to relentlessly pursue those who carry out these unacceptable and distasteful crimes."
Adedicated websitehas been set up by the Welsh Heads of Trading Standards to give people advice about dealing with unwanted doorstep callers.
