The court order comes a day before the crucial bypoll to 18 Assembly seats and one Lok Sabha constituency in Andhra Pradesh for which Jagan's plea to be released on bail for campaign was rejected earlier by the court.
The arrest of 39-year-old Jagan on May 27 became the dominant issue during campaigning with his mother and YSR Congress party's honorary president Y S Vijaya Lakshmi spearheading the canvassing.
The CBI filed a petition before the court of principal judge for CBI cases for carrying out scientific tests (narco and polygraphic examination) on him and another key accused and his financial advisor V Vijaysai Reddy.
"During the investigation it has emerged Jagan being the main beneficiary of all the ill-gotten money through various dubious methods including suspected hawala method and Vijay as the main kingpin and conspirator with Jagan to have alleged committed the offences," the CBI submitted.
Jagan, who has been sent to CBI custody twice, is the repository of entire information, document and details of alleged hawala transactions and he is keeping all the information close to his chest, the CBI said in its petition.
The agency further submitted that the investigation has revealed a chain of circumstances and multiple conspiracy with various persons, companies in Hyderabad and other parts of India and also foreign countries.
"In order to help and aid proper, just fair and fearless investigation into the matter the CBI seeks indulgence allowing the agency for using scientific ways for deriving information from Jagan and Vijaysai Reddy," CBI Superintendent of police H Venkatesh said. MORE
