Seven top Indian athletes, including Asian Games double gold-medallist Ashwini Akkunji, were on Friday handed bans for flunking dope tests earlier this year. This virtually ends their chances of participating in the London Olympics next year.The seven athletes include six quartermilers – Mandeep Kaur, Sini Jose, Mary Tiana Thomas, Priyanka Pawar, Jauna Murmu and Akkunji and long jumper Harikrishanan Muraleedharan.While the six women athletes have been banned for a year, Muraleedharan has been slapped with a two year ban. The decision was announced at the National Anti-Doping Agency headquarters in Delhi . NADA panel head Dinesh Dayal announced a reduced penalty period as the athletes were not found guilty of intentionally taking the banned substances. The maximum suspension stands at two years for the first-time violators.NADA Director General Rahul Bhatnagar said that under the rules, there will be only one reinstatement test, which can be done the next day after their ban period is over. All the atheles can appeal against their ban to the NADA appellate panel.
