New Delhi, June 1 (IANS) The Central Bureau of Investigation (CBI) Wednesday asked the income tax department to provide it phone transcripts of two city-based chartered accountants -- brothers Anil and Radhey Shyam Bansal -- suspected to be involved in money laundering in the 2G spectrum scam.

 
 A CBI official said the income tax department had April 6 handed it a sealed envelope containing records of the tapped phone calls of the brothers. However, the agency wants only those conversations relating to the 2G scam.
 
 "We have sought the relevant transcript of the conversations. The Bansal brothers allegedly are specialised in turning people's unaccounted income into legal funds. They too are involved in the 2G spectrum case," a CBI official said.
 
 A joint team of CBI and income tax officials raided their premises April 11.
 
 The income tax department had intercepted their phones during routine surveillance against tax evasion.
