The officer, Manoj Kumar, has denied the charges saying the entire episode was being blown out of proportion and was part of a "larger conspiracy" to take him out of the case.
Officials said Kumar, an Assistant Director of the agency, has been "suspended pending enquiry" even as he has been removed from the cases he was probing like the Rose Valley chit fund case and some pertaining to the Coal blocks allocation.
While speaking to reporters outside the agency's Salt Lake office in Kolkata, Kumar claimed innocence.
"It is a larger conspiracy to eject me out of the case (Rose Valley). I don't want to comment to be political victim or a victim of cross-fire by the Kolkata Police for the reasons best known to them. I have already offered my cases to be scrutinised by any officer of ED or to a team of officers," he said.
