POLICE are urging residents to be aware of bogus doorsteps traders who pose as handicapped or as ex-convicts trying to turn their life around.

Sherborne neighbourhood police have received reports of ‘Nottingham Knockers’ working in the area.

According to Safe Local Trades, these sellers could claim they are on a rehabilitation course arranged by a probation service or other organisation and are trying to find work.

They offer small household products, such as cleaning items, for sale which are of poor quality and at inflated prices. They could also show a card which looks like a work permit in an attempt to prove their legitimacy.

Residents, especially elderly and vulnerable people, are warned not buy or sell on the doorstep or open the door to strangers.

A spokesman said: “Please make yourself aware of the tactics these doorstep traders use and note that you are under no obligation to open your door or purchase any items.”
