New Delhi, Jan. 6 -- The Serious Fraud Investigation Office (SFIO) has filed a prosecution complaint against fugitive businessman Mehul Choksi, his wife Priti Choksi, former managing director and chief executive officer (MD-CEO) of ICICI Bank, Chanda Kochhar, the same bank's former executive director NS Kannan, former Punjab National Bank (PNB) officers and several others as part of a probe into Choksi's companies that are accused of cheating the banks of over Rs.13,000 crore, people familiar with the matter said on Monday. SFIO, which investigates and prosecutes corporate frauds, has detailed in its complaint, the entire chain of financial irregularities and the role of various accused who allegedly helped Choksi create a fortune before fleeing India in 2017, the people added, asking not to be named. The complaint, filed before a Mumbai court last month, also named Kochhar (who is being investigated by the Central Bureau of Investigation and the Enforcement Directorate in a separate probe against the Videocon Group), Kannan, former PNB employees Gokulnath Shetty, Bechu Tiwari, Yashwant Joshi and Prafful Sawant, and several key functionaries in Choksi's companies. The firms investigated and named by SFIO, include Gitanjali Gems Ltd, Asmi Jewellery India Pvt Ltd, Gili India Limited, Nakshatra Brands Limited, Bezel Jewellery (erstwhile D'damas), as well as several entities based in Hong Kong. Kochhar declined comment on the matter. Kannan didn't take calls and did not respond to a text message. Choksi's lawyer Vijay Aggarwal cited the Kushal Kumar Aggarwal vs Enforcement Directorate and said that SFIO's complaint is not a charge sheet, adding that his "clients cannot be summoned by the court without giving us an opportunity of hearing"....
