The Enforcement Directorate (ED), which has been probing the money laundering aspect of the multi-crore Saradha ponzi scheme, on Wednesday interrogated suspended Trinamool Congress leader Kunal Ghosh for the second time.
Mr Ghosh, who visited the agency's office in Kolkata at CGO Complex, was questioned for nearly two hours.
Sources in the ED told news agency Press Trust of India that Mr Ghosh, a former Trinamool Congress MP, had allegedly received funds from the Saradha group to head its media unit.
"We are probing the flow of funds which Ghosh had allegedly received from the Saradha group and also the money laundering angle," the sources said.
Mr Ghosh was earlier interrogated by the agency in connection with the case in October 2013.
The Saradha group owned the dailies Bengal Post and Sakalbela, which had ceased publication after the scam broke out in April 2013.
Mr Ghosh was initially arrested by a special investigation team of the Bidhannagar Police Commissionerate in November 2013 in connection with the case and later, the Central Bureau of Investigation (CBI) took over the investigation on the orders of the Supreme Court.
Mr Ghosh was granted an interim bail in 2016.
TMC's sitting MP Satabdi Roy, two businessmen Sajjan Agarwal and Sandhir Agarwal, East Bengal Football Club official Debabrata Sarkar and Arindam Das, a close aide of Saradha scam mastermind Sudipta Sen had also been summoned by the ED.
