The chief judge of City Sessions Court Mohd Mumtaz Khan extended the custody of Piyali Sen and Subhojit Sen till April 24 on a plea by the investigating agency for further questioning them to locate a bank locker and properties which have not been identified yet.
They also wanted to quiz them on details of other assets which are not yet known.
The court had earlier granted five days' custody of the duo to the ED on April 17.
This money was transferred to different accounts including to those of Sen's second wife Piyali and Shubhojit, Sen's son from his first wife, apart from buying benami properties, the ED has claimed before the court.
Sudipta Sen was arrested from Kashmir in April last year and has been in the custody of West Bengal Police since then.
The duo, Piyali Sen and Shubhojit, were arrested by the sleuths of the central probe agency after they were questioned for close to two hours with regard to the alleged dubious transactions that led to the Ponzi scam which has duped hundreds of investors across West Bengal, Odisha and Assam.
