Police are warning people about rogue traders in Grantham who are targeting the elderly.
A man, pretending to be deaf, is selling paintings and another man has been calling on doors selling rugs. A third man has been pretending to be from Anglian Water.
A police spokesman said: “Please be aware as they are targeting the elderly. Make sure you check all ID and if you have any concerns ring the company. If you are suspicious of anyone ring the police on 101 or your local NPT team.”
