Kolkata, April 22 (IANS): A city court Tuesday extended the custody of Saradha chit fund scam kingpin Sudipto Sen's wife Piyali and son Subhojit with the Enforcement Directorate till April 25.

"The court today (Tuesday) extended their custody till April 25 when they will have to appear before the court again," said Piyali and Subhojit's counsel Samir Das said.

The duo was arrested April 16 under the Prevention of Money Laundering Act and subsequently remanded to ED's custody till Tuesday when they were again presented before the court.

Probing the multi-crore scam, the ED so far has attached numerous properties owned by the Saradha group including those by Sudipta and his family.

The agency which Sunday interrogated Subhojit's wife Priyanka, has also served a notice to Trinamool Congress Lok Sabha candidate from Balurghat Arpita Ghosh.

Ghosh, a former employee of the Saradha Group, had filed a case against Saradha promoter Sudipta Sen for non-payment of her salary which eventually led to his arrest.

Sudipta and several of his cronies are now behind bars for the scandal which came to light in April last year. The company closed shop across Bengal after being unable to pay back the depositors -- mainly poor people who, lured by the promise of huge returns, parked their life's savings with the firm.

Suspended Trinamool Congress Rajya Sabha member Kunal Ghosh is also under arrest for his alleged complicity in the biggest financial scandal to hit West Bengal.
