The CBI has filed an additional charge sheet in the quid-pro-quo case involving YSR Congress chief Y S Jaganmohan Reddy listing some former ministers of pre-bifurcation Andhra Pradesh and some retired government officials in it.

CBI DIG V Chandrasekhar said the additional charge sheet, which was filed last week, names former ministers of (pre-bifurcation) Andhra Pradesh Dharmana Prasada Rao and Sabitha Indra Reddy, and some retired government officials among others as the accused.

The charge sheet pertains to mine and land allocations to Penna Group when Jagan's father, late Y S Rajasekhar Reddy, was the chief minister of Andhra Pradesh during 2004 to 2009.

The CBI has filed 11 charge sheets in the case and the trial is going on before a local CBI court.

"The (additional) charge sheet pertains to the prospecting licence for a mine given to Penna Group in Kurnool district (in Andhra Pradesh) and land allocation in Rangareddy district (in Telangana)," Chandrasekhar told PTI.

According to CBI, various companies and individuals made huge investments in Jagan's businesses when his father was the chief minister. These investments were quid pro quo for government favours such as land allotments, licences, etc, it says.

Jagan, thus, amassed huge wealth misusing the office of his late father, CBI alleges.
