Research from the Financial Conduct Authority has found that only two in five people over the age of 55 think they can tell when an investment opportunity is fraudulent. Scammers are increasingly targeting this age group because they believe they're more likely to have a lump sum of money to invest. Last year victims lost an average of £32,000 to fraudsters, which the FCA is trying to tackle with its ScamSmart campaign. To discuss the campaign and the research in more detail, Share Radio's Sara Macham spoke to broadcaster Nick Hewer.
