Mandhira Kapur Smith, ex-Sona Comstar Chairman Sunjay Kapur's sister, criticised Sona's treatment of their mother Rani amid a ₹30,000-crore dispute. "There should've been little more respect...Sona threw my mother on street...She was only one who stood behind my father while he built Sona," she said. "Prove...that she's not connected to the company...The name 'Sona' came from my father," she added.
