Andhra Pradesh CID officials are retrieving crucial information from the laptops, hard-disks and various documents seized during the raids conducted at the offices of scam-ridden Satyam Computer Services.
The officials are also taking the help of accounting professionals to understand the details of the issue, a senior official probing the case said.
"We are working day and night on the issue. The probe will take time given the magnitude of the matter," he said.
Raids were also conducted at the residences of Satyam's former chairman B Ramalinga Raju, his brother and former MD Rama Raju and ex-CFO Vadlamani Srinivas on January 11 and 12.
Meanwhile, the CID is likely to quiz a top executive and three directors of the firm's disbanded Board in a day or two to get further information about the scam, he said.
"We are waiting for tomorrow's court decision where bail petitions of former chairman of Satyam B Ramalinga Raju, his brother and former MD Rama Raju and ex-CFO Vadlamani Srinivas will come up along with SEBI's plea for quizzing Raju and CID petition seeking their police custody," he said.
"We are coordinating with other probe agencies like SEBI and SFIO and exchanging information," he said.
CID officials held a two-hour-long meeting today to take stock of the situation.
