On October 20, the High Court rejected the anticipatory bail plea of former government chief whip and BJD MLA Pravat Tripathy in the Artha Tatwa chit fund scam. On Saturday, the CBI interrogated him, for the fourth time, about nomination of chit fund group chief Pradeep Sethy for a state-sponsored cooperative award. So far, there have been several high-profile arrests, including that of former advocate general Ashok Mohanty. But the probe into the Artha Tatwa scam could see many other similar scams tumbling out.
