Police are warning residents in East Cambridgeshire to remain vigilant after reports of rogue traders operating in the district.

Community safety officer, Sue Loaker said officers had received reports of “suspicious vehicles” in East Cambs and said people posing as traders had been knocking on doors in search of work.

She said: “The constabulary is receiving reports from residents of suspicious vehicles in their area. The occupiers of the vehicle have been reported on occasion to approach a property, speak to the resident and ask to complete maintenance work on the property.

“While one of the ‘traders’ keeps the resident talking at the front door, another ‘trader’ is looking for insecurity at the back of the property.

“We urge you never to allow any work to be undertaken on your property by cold callers. The initial quote for the work may appear reasonable, however, once the work is completed and often to a low standard the price is then dramatically inflated.

“These people can be very intimidated convincing and threatening. Sometimes these bogus callers will keep you talking at the front door whilst an accomplice gains entry elsewhere perhaps through your backdoor or an open bedroom window.

“These criminals vary in age and can be either male or female.”

Ms Loaker advised homeowners to keep their front and back doors locked so people could not gain entry to the house unless invited.

Anyone with information should contact Cambridgeshire police on 101.
