The ED chargesheet filed Thursday also details the attachments made by the agency against Modi and his associates in the last few months after it first registered an FIR in the PNB fraud case. It focuses on the money laundering aspect and the role of Nirav Modi and others in perpetrating the alleged fraud, a senior official said. Earlier in May, Central Bureau of Investigation (CBI) filed two chargesheets in the PNB fraud case.
