The Central Bureau of Investigation (CBI) has filed a case against Anil Ambani and his telecom firm, Reliance Communications (RCom), in connection with a massive bank fraud. The charges stem from allegations of misrepresentation, diversion of funds, and default on loans taken from a consortium of Indian banks. Once a telecom giant, RCom has been struggling with insolvency and mounting debt, and this probe adds another layer of complexity to its long-running financial troubles.
