The XIV additional chief metropolitan court allowed the Central Bureau of Investigation (CBI) to take handwriting and signature samples of Satyam Computer founder B Ramalinga Raju, his brother B Rama Raju and the company's former chief financial officer Srinivas Vadlamani in front a magistrate on Wednesday and Thursday.
The CBI, which is now probing the Rs 7,800 crore financial scam at Satyam, also sought the court's permission to subject Ramalinga Raju and the two others to lie detection test. The court is yet to deliver its orders on this petition.
The CBI counsel said that the accused were not forthright in their replies during the interrogation. The CBI questioned all the five accused including Price Waterhouse auditors S Gopalakrishnan and Srinivas Talluri from March 10 to 17. It later sought two more days to interrogate Raju brothers and the former chief financial officer.
