The Enforcement Directorate (ED) has questioned 31 persons on the aspects of money-laundering in the 2G spectrum scam.
In its latest status report filed before the SC, the agency claimed that multi-crore foreign transactions have taken place in the scam.
Senior counsel KK Venugopal, submitting a sealed copy of the report, told a bench of justice GS Singhvi and justice AK Ganguly said the transactions had been traced to at least six countries.
Venugopal defended ED's role and thrashed media reports alleging the agency had slowed down its probe. The senior advocate sought court protection for the ED officers from being harassed through "mischievous news reports."
On perusing the status report, the bench observed: "The status report shows that these people (alleged violators) had connections in many countries."
The bench is monitoring the CBI and ED probe into the 2G scam after CPIL filed a petition before it seeking an inquiry into the irregularities that took place during former minister A Raja's tenure while allocating spectrum.
The violations had caused a loss of over Rs 1.75 lakh crore to the exchequer.
Venugopal informed the bench that ED had sought assistance from foreign authorities in tracking the source of money. He added letters rogatories had been sent to Jersey and Virgin Islands.
The senior counsel did not name the persons under ED's scanner but informed the court that statements of 26 have been recorded.
Lobysist Niira Radia's sister too was asked to furnish some details.
