The CBI has unearthed key evidence of his transactions abroad and has already sent letters rogatory to both aforesaid nations. In response to the letters, the nations have confirmed that there was indeed cash that passed hands between the telecom companies and Raja. The former telecom Minister is believed to have unfairly delivered spectrum allocations to certain telecom companies and is accused of tweaking laws to the advantage of such companies.

With the Enforcement Directorate also joining in the probe, they have sent letters rogatory to as much as 10 countries to look into where the money has been parked and how the money traveled to foreign shores. Some of the countries that Raja have stashed away the money include Mauritius, Cyprus, Dubai, Moscow, Norway, Isle of Man, Jersey Island, British Virgin Island and Singapore.
