In a letter sent by American National Crime Bureau through Interpol to the CBI, the US authorities have said Rao should be put under provisional arrest till all the documents were handed over to India through diplomatic channels for his possible extradition to stand trial in Chicago, official sources said.
The sources said CBI sent the letter to the Andhra Pradesh Police asking them to take action against Rao, who was a close aide to late Andhra Pradesh Chief Minister Y S Rajasekhara Reddy.
Asked about the indictment by the US Federal Jury, he said, "how can I react on assumptions".
The US also informed CBI that Interpol had already been approached for issuance of Red Corner Notice against Rao, who was charged in the US in an alleged international racketeering conspiracy involving bribes worth USD 18.5 million to state and central government officials in India to allow the American firm undertake mining of Titanium minerals in Andhra Pradesh.
As per the US laws, all the accused will be produced before Chicago court where they can either enter into a plea bargain or face the trial.
