Out of the registered cases, 1,435 cases were by anti- corruption branch of the Delhi Government, Police and CBI whereas 2,877 such cases were registered by the MCD's vigilance wing. The Anti-Corruption branch has registered 40 cases under different sections of Prevention of Corruption Act against 100 MCD officials and some other private persons. Most of the tainted MCD officials, working at middle and senior levels like zonal incharge, superintendent and executive engineers, have over two to three such cases against them, the RTI reply said.

Exercising his right to information, Vivek Garg, an RTI activist and advocate, sought data related to cases awaiting prosecution in the last 25 years.

"The information was initially denied by the PIO. I filed first appeal after that they sent me 96-page list containing name of officials in MCD against whom departmental action and police cases are pending," Garg said. Even more discouraging is the fact that three officials retired from the MCD without completing the probe in such cases. "MCD has become the nerve centre of corruption. Accused in connivance with other corrupt officials have avoided probe and prosecution in cases against them," Garg said.
