COLD callers have been knocking on doors attempting to sell items.

The sales group, known as 'Nottingham Knockers' traditionally carry large holdalls containing cleaning items, which they offer for sale and have been seen in Malvern this week.

Some residents are reporting that if they decline to purchase any goods, the individuals use pressurised selling techniques causing the home owner to feel intimidated.

West Mercia Police are advising that if any sales person comes to the door selling any products, do not be persuaded to part with money for products that aren't need or are of poor quality.

Residents are also advised to use precautionary measures such as a door chain and to ignore callers if they are unsure who it may be.

Anyone selling products on a door-to-door basis are required to be in possession of a valid pedlars certificate; a card with the person's name and photograph is NOT sufficient.

If in doubt, do not answer the door and report sightings to the non-emergency police line on 101.
