"Kunal Ghosh has written a 91-page letter in Bengali to us urging about various things regarding the investigation. We are looking into the matter," a senior official of the Enforcement Directorate, said.
Ghosh, who is in police custody in connection with the scam in which lakhs of poor depositors were duped, was arrested last year after he was suspended from the TMC for the anti-party activities.
Recently, ED's zonal office in Kolkata issued summons to about 15 people involved in fund transactions of the scam, which came to the fore early last year when the duped investors demonstrated to air their grievances.
The summons followed the ED's attaching Rs 105.62 crore worth of assets belonging to various entities involved in the case including Sudipta Sen and his wife Piyali.
