Asian champion shot-putter Manpreet Kaur has been caught in the dope net after testing positive for a banned stimulant. She has been tested positive for stimulant dimethylbutylamine. The test was conducted by National Anti-Doping Officials during the Federation Cup National Championships held in Patiala from 1st to 4th June. She has not been put under provisional suspension as dimethylbutylamine is a specified substance under the WADA Code but India will lose the gold medal she won in Bhubaneswar if her confirmatory urine sample 'B' test also returns positive. Manpreet has already qualified for next month's World Championships to be held in London. Since, Dimethylbutylamin comes under the unspecified category of the World Anti-Doping Agency (WADA), Kaur is eligible to take part in the world meet. Manpreet had set a national record in the first leg of the Asian Grand Prix meet in Jinhua (China) with a throw of 18.86m which fetched her a gold as well as a World Championships berth. Later, she won a gold each in the Federation Cup, Asian Championships and the National Inter-State Championships which concluded at Guntur yesterday.
