CBI has begun an inquiry into the alleged inflated credit facility availed from banks by Adani Group by over-invoicing for importing power sector equipment to the tune of Rs 2300 crore. CBI sources said the Adani Group had allegedly taken credit facilities from several public sector banks for equipment for power infrastructure. When contacted, Adani group officials said they were not aware of any such development and no such communication is received from CBI in this regard. The agency has filed a preliminary enquiry on the basis of a reference from Directorate of Revenue Intelligence (DRI) alleging that the company purchased the equipment from South Korea and China as power sector imports attract very less duty.
