Imran, a Rajya Sabha MP, reached the agency's office in Salt Lake here and will be questioned about his connections with the defunct group owned by jailed Saradha Chairman Sudipta Sen.
Sources said the ED wants to grill Imran as he was the Executive Editor of a Bengali publication 'Kalam' which was owned by Sen but it was later sold to another business group.
ED sleuths want to know details of Imran's financial income and other interests while working for the publication, the sources said. The agency is likely to confront Imran with some documents it has seized sometime back in this case.
The ED has earlier quizzed TMC MP Mithun Chakraborty and Kunal Ghosh and state Textile minister Shyamapada Mukherjee in this case.
A criminal case under the provisions of the Prevention of Money Laundering Act (PMLA) has been registered by the agency last year to probe the ponzi scam that came to light last year after thousands of investors alleged they were duped of their hard earned money by the schemes run by Saradha group.
