Mumbai: The Central Bureau of Investigation (CBI) on Thursday registered an FIR in connection with alleged irregularities in the Rs 3,250 crore ICICI Bank-Videocon loan case and raided the Videocon headquarters in Mumbai and Aurangabad.

The search operation started Thursday morning and also covered offices of Nupower, a company operated by ICICI Bank’s former CEO Chanda Kochhar’s husband Deepak Kochhar and Supreme Power.

It is alleged that Videocon promoter Venugopal Dhoot allegedly invested crores of Rupees in Nupower months after the Videocon group got Rs 3,250 crore as loan from the ICICI Bank in 2012, officials said.

The agency had registered a preliminary enquiry against Videocon promoter Venugopal Dhoot,Deepak Kochhar and unidentified others in March last year, they said.

A PE is a precursor before the agency lodges an FIR to probe criminal charges on the basis of evidence collected during the former exercise.

The agency has now converted it into an FIR which means a full blown investigation has been started by the agency after registration of a case.

The details of the FIR and names of the accused are awaited, they said.
