CBI sources said a team might soon visit the Nagpur-based IBM in connection with its probe related to alleged scam in allotting licences with regard to mineral exploration in 62 blocks around country's coastline.
The agency has demanded that all the documents related to expression of interest be submitted by various applicants besides the minutes of meetings where modalities of the block allocation were decided by the bureau officials.
The CBI had registered a preliminary enquiry in connection with the alleged favours extended to the companies by the unknown officials of IBM while awarding licences for offshore mineral exploration.
It is alleged that four beneficiaries companies owned by the family members of an Indian Revenue Service officer has bagged nearly half of the blocks despite lacking necessary qualification, they said.
The government in June 2010 had placed 62 blocks worth 800 sq km each for mineral exploration out of which 28, nearly half, were bagged by companies owned by family members of the former Enforcement Directorate official.
The final award of licences had been put on hold after aggrieved parties approached the Bombay High Court and the Andhra Pradesh High Court seeking their cancellation.
The companies allegedly owned by the son and brother of the officer are based at the same address on Kasturba Gandhi Marg in the national capital, they said.
