The CJM court judge P L Satpathy accepted CBI's petition seeking remand of Mishra who was arrested by the central investigating agency yesterday after being on the run for the last nine months.
MFL has allegedly duped investors of Rs 500 crore by floating several ponzi scheme companies in Odisha.
CBI alleged the accused had floated 10 companies, including a television channel and over a period of time is alleged to have collected Rs 500 crore from depositors.
Speaking to reporters outside the court, Mishra claimed MFL operated as per RBI guidelines and has been in business for 30 years. He also denied he had gone into hiding.
The agency sleuths had raided his residence here on December 8 and seized some documents.
