Criminal Bureau of Investigation will probe the 'unique' Rs 7,800-crore (Rs 78-billion) Satyam [Get Quote] fraud case, the country's biggest ever corporate scam, more than a month after it came to light.

CBI on Wednesday announced that it will set up a multi-dimensional team to probe the 'unique' fraud, which involves Satyam founder B Ramalinga Raju and his family members.

"We have received a notification from the Centre to take over the Satyam Computer Services scam case from the Andhra Pradesh Police. We are going into various aspects of this multi-dimensional and unique scam. We will soon register the case," a CBI spokesman told reporters.

He said CBI proposes to establish a multi-disciplinary investigation team with headquarters at Hyderabad, where the IT major is headquartered. "A joint consultative and coordination mechanism is being worked out with concerned ministries, departments and institutions for providing necessary assistance to the CBI," he added.

While the spokesman remained evasive to questions on when the cases would be registered, CBI sources said records and other materials associated with the probe was being taken over by the agency.
