After being asked by the central probe agency, Srinivasan appeared before CBI at the Dilkusha Guest House here. The agency sleuths are currently questioning him, sources said.
CBI is probing the alleged investments made by Srinivasan's company India Cements in the firms promoted by the Kadapa MP during the tenure of his father Y S Rajasekhara Reddy as Andhra Pradesh Chief Minister, the sources said.
Some other cement companies are also likely to be asked about water and limestone allocations made to them during Rajasekhara Reddy's tenure.
The CBI, in its three charge-sheets filed against Jagan and others, has alleged that he and his father hatched a conspiracy to defraud the government, and the state government granted some favours to certain firms, which made investments in Jagan's businesses as a quid pro quo.
Jagan is currently in judicial custody till June 25 and has been questioned by the CBI.
