The central bureau of investigation is set to question former communications and IT minister Dayanidhi Maran again in connection with the 2G spectrum allocation scam, CBI source said.
The questioning, with respect to the Maxis-Aircel deal, is likely by March-end, they said.

The investigating agency is also in the process of sending a letter rogatory to the Malaysian government seeking help in probing the Maxis-Aircel deal, which took place during Maran’s regime, they said.

A letter rogatory is a formal letter of request from a court to a foreign court, seeking judicial assistance, usually in the process of recording evidence.

The agency needs help from the Malaysian police to investigate the investments made by the Malaysia-based Maxis Communications in the deal and later allegedly in the Marans-controlled Sun Television network. With the help of Malaysian authorities, the agency hopes to find details of the alleged role of Dayanidhi Maran, his brother Kalanidhi Maran and maxis owner T Anand Krishnan
.
Earlier in February, the enforcement directorate registered a money laundering case against the Maran brothers in the 2G spectrum scam. The case pertains to an allegedly huge investment Maxis made in Sun TV.

Dayanidhi Maran had to quit the cabinet after these allegations of favours granted to Maxis.

In December 2006, the department of telecom (DoT) issued 14 licences to Maxis-controlled Aircel Communication. Maxis allegedly invested Rs 550 crore in Sun TV from 2007 to 2009, followed by another investment of Rs 111 crore in the media group owned by the Maran brothers, the sources said.

The CBI had searched the premises of the Maran brothers in October last year after registering a case against the Marans, Krishnan and Ralph Marshall of Maxis. It also named Sun TV and Maxis in the first information report (FIR).
