The apex court bench headed by Justice GS Singhvi said "the team will have five officers from the Central Bureau of Investigation (CBI) and one from Income Tax department". The six-member team will work under the supervision of two senior officers of the CBI.
The intercepts of Radia's telephones led to the unearthing of the 2G scam.
The six-member team in turn will be supervised by a Superintendent of Police (SP) rank official and the entire set would be under a deputy inspector general of the premier investigative agency, the court said.
The court gave the CBI four months' time to complete the analysis of the Radia tapes and submit its report to it.
Radia and her associates' phones were put under surveillance by the Income Tax department after the home ministry received an anonymous letter alleging her foreign connections and her spectacular rise in a short span of a few years.
Following the letter, the Income Tax department was asked to investigate the matter.
