New Delhi: Former Asian silver-medallist Sumit Sangwan's positive dope test has left the Indian boxing fraternity shocked with national coach C A Kuttappa lamenting the accomplished pugilist's "wretched luck". The 26-year-old Sangwan was crowned 91kg category national champion in October and was preparing to return to his preferred 81kg division when it came out that he has tested positive for a diuretic acetazolamide.

"He had just won the national title, was coming along nicely for the 81kg division, now this has happened. I am in shock, his track record has been clean and I would like to believe it is a mistake," Kuttappa told PTI after returning from the South Asian Games in Nepal. "He has been so unlucky. After he won the Asian silver 2017, he got injured, that required surgery. He was once again picking himself up and I am told a mistake has led to this now," he said. Indian Boxing's High Performance Director Santiago Nieva revealed that Sangwan has left the national camp in Patiala. "He has taken leave to deal with this issue. It is shocking," he said. The boxer is an Olympian (2012, London). A Boxing Federation of India official said there has been no response from him on whether he wants a 'B' sample test or not.
