Tripathy, who was yesterday arrested by CBI on charge of criminal conspiracy and accepting of huge sums of money from chitfund company Artha Tatwa Group, was produced before the special CBI court which remanded him to the custody of the central investigating agency till November 13.
The MLA's lawyer Omprakash Ray opposed CBI's petition.
"As Tripathy has been interrogated four times before the arrest, there is no need for CBI to take him on remand," Ray said, adding the investigating agency has no sufficient evidence against his client.
Before being whisked away by the police to the court, Tripathy claimed he was not connected with the chitfund scam.
Earlier in the day, doctors conducted a health check up on Tripathy at the CBI office here and found his health condition and blood pressure well within normal parameters.
