Officials said four leaders have been issued the notices.
Earlier this week, Karnataka Congress President DK Shivakumar had told reporters after finishing his questioning session with the ED in Delhi that he was questioned about certain transactions made by him to this company in the past.
“Surprisingly, they (ED officials) have asked me about the payment from one of my trust, from me and my brother, to Young Indian,” he told reporters on September 19.
Shivakumar said he had sought more time from the agency to furnish details about his assets and liabilities.
Congress President Sonia Gandhi and her son and MP Rahul Gandhi, apart from some other Congress leaders, have been questioned by the ED over the last few months in the National Herald money laundering case.
The National Herald newspaper is published by Associated Journals Ltd and the ED had in August searched the Young Indian office located at ITO in Delhi as part of this probe.
