A local court on Monday sent Satyam's former chairman B Ramalinga Raju, his brother Rama Raju and three others to CBI custody for seven days from Tuesday.

Besides the Raju brothers, the CBI would be quizzing Satyam's former CFO Vadlamani Srinivas and audit house PricewaterhouseCoopers' partners S Gopalakrishnan and Talluri Srinivas in connection with the Rs 7,800 crore (Rs 78-billion)accounting fraud at Satyam Computer.

The court also dismissed the bail petitions of Gopalakrishnan and Srinivas.
