According to media reports, former Union Textile Minister and Lok Sabha MP Dayanidhi Maran and Sun Group chairman and managing director Kalanithi Maran were questioned by the Central Bureau of Investigation (CBI) on the Aircel-Maxis deal.

The CBI has questioned the former Telecom Minister Dayanidhi Maran in connection with a case against him, his brother Kalanithi Maran and Malaysian business tycoon and head of Maxis Communications T. Ananda Krishnan of allegedly coercing the former owner of Aircel Televentures C. Sivasankaran into selling his equity in Aircel.

Dayanidhi Maran allegedly denied Sivasankaran's firm seven pending 2G spectrum licences in various circles, and the Point of Interconnection facility from the state-owned BSNL.

The CBI alleged that an illegal gratification of Rs 549.96 crore accrued to the Maran brothers from the purchase of Sun Direct TV shares by Astro All Asia Networks Plc, a related company of Maxis Communications, allegedly at a highly inflated rate, media reports suggested.
