The apex court had on September five ordered a CBI probe into the death of M K Ganapathy, a deputy superintendent of Karnataka police, saying there were "startling facts" in the case which needed to be probed in a fair manner.
Led by BJP state president B S Yeddyurappa, a large number of party leaders and workers turned up at the Mourya Circle here asking George to step down as a minister, saying otherwise the probe might be influenced.
Sriramulu said he was a minister when Yeddyurappa was the Chief Minister but resigned when his name figured in the Lokayukta report in connection with illegal iron ore mining.
The 51-year-old Ganapathy was found hanging from a ceiling fan in a room at a lodge at Madikeri in Kodagu district on July seven last year, with the mystery surrounding the death raising a huge political controversy. Prior to the alleged suicide, Ganapathy had told a local TV channel in an interview that the then Home Minister George and two senior police officers A M Prasad and Pranab Mohanty would be responsible "if anything happens to me".
