The Enforcement Directorate has issued summons against Maran brothers — Dayanidhi and Kalanidhi — in connection with its probe in the Aircel-Maxis deal in the 2G spectrum allocation case. The agency has summoned both the brothers, former Union Minister Dayanidhi Maran and his brother and Sun TV MD Kalanidhi Maran, under the provisions of the Prevention of Money Laundering Act (PMLA). While Dayanidhi or his authorised representative has been asked to depose before the agency on March 20, Kalanidhi or his authorised agent has been asked to meet the investigators a day later, with documents of their personal transactions and those dealing with their businesses.
