The Bidhannagar City Police, which is probing the Saradha group scam, on Wednesday refused to take cognisance of the video footage aired by a local television channel in which, before his arrest, Trinamool Congress MP Kunal Ghosh made revelations about links of senior party leaders with the scam-tainted group.

“The investigations are not dependent on what an accused person is saying,” Arnab Ghosh, Deputy Commissioner (Detective Department) of the Bidhannagar City Police told journalists. Mr. Ghosh’s role was not limited only as the CEO of the media arm of the company; he also played an important role in the company’s policy making, the police officer said.

There are also plans of joint interrogation of Saradha Group CMD Sudipta Sen and Mr. Ghosh, the police said.

Meanwhile, Trinamool Congress MP Subhendu Adhikari told journalists at a press conference that he had filed defamation case against Mr. Ghosh and the channel that aired the video footage.
