The CBI has filed a closure report in a Delhi court in a case involving former Prasar Bharti CEO B S Lalli saying it found no substantive evidence against him on charges of committing fraud and conspiracy in awarding of broadcasting rights for Commonwealth Games.

The agency has filed the closure report before Special CBI Judge Talwant Singh who has kept it for consideration on August 4.

The CBI, in its closure report, said that they have not found substantive evidence against Lalli and Managing Director of Delhi-based Zoom Communications Wasim Dehlvi, also the resident director of UK-based SIS Live.

The CBI had last year booked both Lalli and Dehlvi for the offences punishable under section 120-B (criminal conspiracy) and 420 (cheating) of the Indian Penal Code respectively.

The probe agency had alleged that a major portion of Rs 246 crore contract given to UK-based SIS Live by Prasar Bharti for "production and coverage" of 2010 CWG was sub-contracted to Zoom Communications for only Rs 176 crore resulting in loss of nearly Rs 100 crore to the exchequer.

In its FIR, the CBI had alleged that a number of conditions were relaxed in favour of SIS Live, including a provision pertaining to sub-contracting to Zoom Communications.

During its investigation, the CBI had also probed whether Doordarshan's decision of not covering 10 of the 17 CWG events through in-house production was "malafide".

It had alleged that Doordarshan initially decided to cover the 10 sporting events but later cut them down to three which was allegedly done to favour the private contractor.

The case was referred to the CBI by the Prime Minister's Office after considering the Shunglu committee report and the one given by Cabinet Secretary K M Chandrasekhar.

In its report, the Shunglu committee had fixed the responsibility for providing "undue benefit" to SIS-Live and Zoom Communications primarily on Lalli and former Doordarshan Director-General Aruna Sharma and had said that they cannot be recused from the acts of omission and commission.
