Nirav Modi. File Pic

Almost four months into the investigation of the Rs 11,400-crore PNB scam, the Central Bureau of Investigation (CBI) on Monday filed a charge sheet against Nirav Modi and 24 others, including senior bank officials. This is the first charge sheet that has been filed against the absconding jeweller since the CBI and ED registered cases against him. Sources said that while Modi is suspected to be in Honk Kong, Mehul Choksi is most likely in the US.
