Bloomberg’s William Mellor talks about Bloomberg Markets magazine's report on events in Indonesia that have led the country's central bank to ban Citigroup Inc. from issuing new credit cards for two years and from taking on new wealth management clients for a year.   Citigroup has been shaken by the death of an Indonesian small businessman and allegations of embezzlement by a female manager at the Citigold wealth-management department. Mellor speaks with Erik Schatzker on Bloomberg Television's "InsideTrack."
