"Let us see what more is there for them to ask me. It seems they feel I am the only person who knows about Sudipta Sen (arrested Saradha Group promoter)," Ghosh told reporters at the Bidhannagar Police Commissionerate, which is probing the scandal.
Ghosh, accused by Sen of involvement in the state's biggest financial scandal, was also interrogated by the Serious Fraud Investigation Office (SFIO) in New Delhi Thursday and Friday.
Sen has accused Ghosh of blackmailing him and barging into his office with miscreants and extracting a sale deed for a media house which Sen owned.
The journalist-turned MP, who was earlier suspended by the Trinamool for being "anti-party", has been questioned multiple times by West Bengal Police, more after his suspension from the ruling party.
Ghosh, who earlier headed Saradha's media arm, has repeatedly claimed he was being made a scapegoat and demanded a Central Bureau of Investigation (CBI) probe.
While the CBI has not formally taken over the Saradha probe, other central agencies - Enforcement Directorate, SFIO and SEBI - are probing the matter.
The Saradha scandal came to light in April. The company closed shop across West Bengal after it failed to pay back the depositors -- mainly poor people who, lured by the promise of huge returns, parked their life's savings with the firm.
As the company went bust, there was a spate of suicides by agents and investors and protests across the state.
