Special Judge Talwant Singh dismissed the bail plea of OC's former Secretary-General Lalit Bhanot and its ex-Director General V K Verma.
"Bail applications of both the accused are dismissed," the judge said and also extended their judicial custody till Apr 21.
Bhanot and Verma were arrested on Feb 23 by CBI for striking a Rs 107 crore deal with a Swiss firm in procuring the Timing, Scoring and Result (TSR) System for the Commonwealth Games.
The CBI had told the court that they were among key personnel in CWG OC and were instrumental in allotment of contract for TSR System to Swiss Timing in a pre-planned and pre-mediated manner at an exorbitant rate of approximately Rs 107 crore, thereby causing a huge loss to the government.
CBI has registered a case against the two under sections 120B (criminal conspiracy) and 420 (cheating) of IPC and various sections of Prevention of Corruption Act, along with Switzerland-based firm Swiss Timing Ltd and other unnamed persons.
The investigating agency had earlier slapped three more charges of fraud, forgery and cheating on the duo.
In its FIR, the agency said in the Expression of Interest (EoI) for the ward of contract, it was made out had that only the Swiss firm had met the laid down criteria.
