Federation of Karnataka Chambers of Commerce and Industry (FKCC) on Monday said that the Central Bureau of Investigation (CBI) booking Aditya Birla group Chairman Kumar Mangalam Birla in the coal block allocation case would adversely affect investment in India. R. Shivakumar, FKCCI president, said that the coal block which was reserved for the public sector was partially allocated to the private sector after the completion of the allotment process and it cannot be termed wrong-doing after eight years.
