Suffolk Trading Standards has warned households to beware of so-called ‘Nottingham Knockers’ in Stowmarket and Sudbury trying to use pushy sales tactics to sell everyday household goods at high prices.
The dishonest salesmen claim to be on a youth offending scheme attempting to mend their ways.
A spokesman for Suffolk Trading Standards said: "Trading Standards always advise residents to refrain from buying at the doorstep and not to buckle to pressure from salespeople offering supposedly one-off 'buy it now' low prices.
"These Nottingham Knockers work in groups across the country but they are not involved in any officially recognised offender rehabilitation programme and many do not possess Pedlar's Certificates, which are issued by police."
Anyone approached by the salesmen are asked to report them to Trading Standards on 03454 040506, or Suffolk police on 101.
