In a major boost to CBI''s probe in the 2G spectrum allocation scam, the Supreme Court of Mauritius has directed the Attorney General there to collect and provide, as soon as possible, information about companies allegedly involved in the case as sought by the agency through its judicial requests.

The CBI expects that after this order, it will be able to get all the information sought by it through Letter Rogatory about companies, which were allegedly involved in the scam, within three to four weeks.

The move will help the CBI in filing third charge sheet in the case, sources said.

As many as 10 different entities named in connection with the 2G scam have a common address -- The Les Cascades Building on the Edith Cavell Street in Port Louis.

The CBI has sent its Letter Rogatory seeking details of business and financial transactions of these companies to unravel the money trail of companies which are under scanner in the spectrum allocation case, agency sources said.

A team of CBI officials has also gone to Mauritius in this connection and is likely to return by Sunday, they said.

The CBI will be sending another team to Cyprus where some companies allegedly involved with the Unitech Wireless, one of the accused in the first charge sheet filed by the CBI, are located, they said.
