Swiss Bank account holder Radha Timblo, whose company is being probed for illegal export of iron ore, is expected to be questioned Tuesday by the Enforcement Directorate (ED) for a third time in a month.
An ED official told reporters that Timblo had been summoned to appear before the central government agency Tuesday.
"She is being investigated for under-invoicing of documents related to iron ore export. We are questioning her on various aspects of the case," the official said Monday.
Also Monday, ED officials also questioned Vijay Kumar, general manager of K.B. Steels, a Bellary-based company which had also been accused of exporting iron ore from Goa's Mormugao Port Trust.
Radha Timblo's name was revealed by the central government to the Supreme Court along with the names of two other Indians. All of them were said to be operating Swiss bank accounts.
Her son Chetan has also been quizzed by ED.
