Long-distance runner Kiranjeet Kaur, who won the Tata Steel Kolkata 25K among the Indians last year, has been handed a four-year ban by World Athletics' anti-doping body for returning positive for a banned substance in a test conducted in Doha. The National Dope Testing Laboratory has been under suspension from the World Anti-Doping Agency and so Kaur's samples were tested in the WADA accredited laboratory in Doha.
