New Delhi: The Central Bureau of Investigation (CBI) might have delayed the arrest of sacked chairman of Commonwealth Games Organising Committee (CWG OC), but is preparing to keep him in jail for a longer time.

The CBI is likely to file a chargesheet against Kalmadi by the end of this month.

Interestingly, it would be the first chargesheet filed by CBI in connection with the CWG scam though the investigating agency has registered 10 FIRs in the case.

Court granted bail to other OC officials including TS Darbari, Sanjay Mahendroo and Jaychandran due to lack of a chargesheet, but Kalmadi is unlikely to enjoy such a legal leverage.

CBI will file the chargesheet regarding the irregularities in awarding contract of Time, Scoring and Result (TSR) system to a Swiss company.

Charges are that Kalmadi along with General Secretary VK Verma,Director Lalit Bhanot and other officials gave the TSR contract to a Swiss company for Rs 107 crore instead of giving it to a Swiss company at Rs 46 crore.

Not only this, the Swiss company was later paid Rs 142 crore for the same contract, causing a loss of Rs 96 crore to the public exchequer .

A senior official of CBI said there were evidences against Kalmadi and others for helping companies which are enough to prove the corruption charges under the Prevention of Corruption Act.

“We have not found evidence regarding payment of bribery and investigations are still on to establish that. But, that won’t prove a deterrence in filing the chargesheet,” said the senior official.

He added that a supplementary chargesheet will be filed after evidences regarding bribery are found.
