“We have filed an application in a Hyderabad court that we would like to do a polygraph test on Raju. Because we feel that Raju has not shared everything with us. We need more evidences. This is a case of corporate fraud," CBI Director Ashwani Kumar told reporters in a press conference here.
Besides Raju, the CBI also wants his brother B. Rama Raju and former Chief Financial Officer (CFO) Vadlamani Srinivas to undergo the test.
