Serious Fraud Investigation Office (SFIO) will file its chargesheet against Vivo this month in an alleged fund diversion case, Moneycontrol reported, citing government sources. This comes after SFIO launched a probe into Chinese smartphone makers following a Registrar of Companies (RoC) report alleging fund diversion of around ₹6,000 crore.
