In its report to CBI on overlays scam, CVC said, the committee had taken equipment on rent at an inflated 42.34 crore rupees against the actual cost of 2.80 crore, thus giving undue benefits to the companies.

Besides, the investigators of the anti-corruption watchdog have found indications of collusive bidding, cost of renting items far higher than the cost of procurement, unreasonably high rate on supplied items, double payment and inferior quality in the overlays work.

In its report, CVC also said, there was no cooperation from OC officials in furnishing documents, clarifications and information during its probe in the alleged scam.
