during audit,i have come across some cases in NBFC'S (that deal with gold loans),wherein gold pledged by a customer is sometimes repledged by the company(without the knowledge of the customer) to another company.I;ve heard my seniors say that it is a case of fraud.Can someone elaborate on how this constitutes a fraud & how to detect such cases?
