The case was registered here against five former officials, who were posted as deputy municipal commissioner (DMC) of UMC between 2002 and 2009 and head of a private firm, following an inquiry, SP ACB Sandeep Karnik said.
The state government had ordered an inquiry on the basis of objections raised by auditors during annual audit of the civic body in 2010, he said.
During the course of investigation, it was found that the five former DMCs and owner of private firm Computer Aids Company, were allegedly involved in financial irregularities between 2002-03 and 2008-09 favouring several property owners, the ACB officials said.
A case has been registered under relevant sections of Prevention of Corruption Act, 1988 against the accused, the ACB added.
