Bandyopadhyay was produced at the CBI-designated Special Chief Judicial Magistrate's court after completion of the six-day remand.
Though the CBI in its petition to the court had sought eight days remand for the TMC MP, judge P K Mishra allowed the central investigating agency four days of custody.
Reacting to the court order, Bandyopadhyay said, "They (CBI) will not free me till Parliament runs smoothly over the demonetisation."
The CBI counsel told the court that though Bandyopadhyay was in remand for six days, the investigating agency could not extract detailed information due to non-cooperation of the TMC MP.
