A 32-year-old man and a 59-year-old man, both from Bluntisham, were arrested on suspicion of fraud and bailed until May 12. An 18-year-old man from Cambridge was also arrested on suspicion of being involved in a series of frauds and bailed until May 5. The day of action (Wednesday, April 9) involved teams of police officers working alongside officers from Cambridgeshire County Councils Trading Standards Service. Rogue trading is when traders cold-call houses offering a service like paving, gardening or tarmacking. They often target the elderly and vulnerable and deliberately overcharge for unnecessary or unsatisfactory services or goods. Work is often left unfinished and often intimidation is used to get payment. The national operation aims to tackle mis-selling, deceit and failure to give cancellation rights to customers. Detective sergeant Jodi Bailey said: This type of crime is particularly appalling because its victims are often those who are most vulnerable and are defrauded of large sums of money. Our advice to residents will always be not to use cold callers and to ask for a business card so you can consider what is being offered, at your leisure. Only 10 per cent of all rogue trading incidents are reported to police without the publics help it is harder for us to bring offenders to justice. Cambridgeshire County Councils cabinet member for enterprise and skills, Councillor Mathew Shuter, said: This is another excellent example of effective partnership working between us and the police. Rogue traders will not be tolerated in our county and the operation this week is part of our on-going work to protect the elderly and vulnerable community.
