A city court on Thursday granted five days custody of the wife and son of Saradha-scam accused Sudipta Sen to the Enforcement Directorate (ED).
Piyali Sen and her son Subhojit were arrested by the ED on Wednesday under provisions of the Money Laundering Act.
They were presented before the City Sessions Court on Thursday and were granted custody till April 22.
The Saradha Group that had through various Ponzi Schemes collected money worth a few hundred crore went bust in April last year.
Thousands of investors across West Bengal, Odisha and Assam were duped.
Later that month, Group Chairman, Sudipta Sen, was arrested from Kashmir and has since then been in the custody of West Bengal police.
Piyali and Subhojit were arrested almost a year later after being questioned by the ED over their alleged involvement.
