Andhra Pradesh IT Minister Ponnala Lakshmaiah today appeared before the CBI in connection with a case pertaining to alleged illegal assets involving YSR Congress president Y S Jaganmohan Reddy even as the agency continued for the fifth day the custodial interrogation of the Kadapa MP. CBI, which had summoned the minister, is likely to examine him over Government Orders (GOs), issued during 2004-09 by the Irrigation department, when he was the Major Irrigation minister in the cabinet of late Y S Rajasekhara Reddy, on supply of water from river Krishna and Kagina to some cement firms, which in turn allegedly made investments in Jagan-owned businesses. The CBI has filed three charge sheets filed against Jagan and others in the disproportionate assets case.
