"I am cooperating with them (SFIO)... they wanted to know where the money is," Ghosh told reporters coming out of SFIO office where he was questioned for more than eight hours between 11am and well past 7 pm.
According to sources, Ghosh may be questioned again on October 21.
Ghosh, who was the CEO of the Saradha media group, had earlier threatened to disclose names if he was arrested in the scam and demanded an inquiry by his party saying he had much to tell the leadership.
The Saradha scam, in which lakhs of investors were duped, came to light in April after which group Chairman Sudipta Sen was arrested along with two others from Sonmarg in Jammu and Kashmir.
According to sources, Ghosh was on Thursday asked about sourceof funding for Saradha group and about the reasons behind Sudipto Sen getting into media business.
Ghosh was suspended from the Trinamool Congress last month. He was summoned by the police in Kolkata six times in the past one month in connection with the scam.
A few days ago, Somnath Dutta, a senior executive with the Saradha media and a close aide of Ghosh was remanded to police custody for seven days in connection with the case.
