Calcutta, Aug. 13 :    Calcutta, Aug. 13:  Former state tennis champion Amit Chaturvedi passed away at a city nursing home Saturday night. He was 33 and suffering from kidney disorder. A genial man full of enthusiasm and warmth, Chaturvedi honed his tennis skills at the South Club under Akhtar Ali and Jaidip Mukerjea. A top-ranked Bengal player at both junior and senior categories, Chaturvedi won several titles at the state and national level. He represented Bengal at the National Games as well as the inter-state meet. While at his peak, Chaturvedi's career was cut short by renal failure resulting in a kidney transplant about five years ago. His playing days were over, but Chaturvedi kept himself associated with the sport in other capacities. He formed a sports promotion firm with his brother and friends, which has so far conducted eight meets at the state and national level.
