HYDERABAD: Corporate Affairs Minister Salman Khurshid said today investigations into the multi-crore accounting fraud in Satyam Computer is almost complete, and a final report from the enforcement directorate and the internal revenue services is awaited.

"The investigation as far as CBI and the ministry of corporate affairs is concerned are more or less over... may be some minor things still needs to be done," Khurshid told reporters on the sidelines of a national conference on corporate governance here.
