CBI sources said that Poddar was being questioned for his business transaction with painter Subhoprasanna, who is considered close to ruling Trinamool Congress in West Bengal and is also on the scanner of CBI and Enforcement Directorate (ED).

Poddar had allegedly sold his firm to the painter, who in turn re-sold it to Saradha group chief Sudipto Sen.
    
ED had earlier interrogated Subhoprasanna for his business dealings with Sudipto Sen and allegedly found discrepancies in his statement and the books of accounts of the firm which he sold to Sen.

The painter had submitted documents to ED which the agency was scrutinising at the moment.
