Indian 400m runner Ashwini Akkunji, a gold medallist at the Commonwealth and Asian Games, is facing a two-year ban for doping on Monday after her \"B\" sample tested positive for steroids. Athletics Federation of India director Manohar Lal Dogra confirmed the positive results for Akkunji and fellow 400m runner Priyanka Panwar, adding that they would now appear before a National Anti-Doping Agency (NADA) disciplinary panel. The duo were among eight athletes who have failed drug tests in recent days. The \"B\", or second, samples of Sini Jose, Jauna Murmu and Tiana Mary Thomas also tested positive last week. The eight were provisionally suspended pending the testing of their second samples. Akkunji was part of the women\'s 4x400m relay team that won the gold medals at the Delhi Commonwealth Games and Asian Games in Guangzhou, China, last year along with Mandeep Kaur and Jose. Akkunji also took the 400m hurdles Asiad title. India has never won a track medal at the Olympics and the women\'s 4x400m relay team was seen as the country\'s biggest hope of a podium finish at next year\'s Games in London. Indian Sports Minister Ajay Maken last week sacked Yuri Ogorodnik, the Ukrainian coach of the 400m runners. The sports ministry also appointed retired judge Mukul Mudgal to head an inquiry into the doping scandal. He is expected to report within six weeks. The athletes have all protested their innocence and blamed contaminated food supplements for the results. They have also said that there were not enough doctors to advise them on which supplements to take. Meanwhile, a NADA team on Monday conducted raids at the Sports Authority of India\'s centre in southern city of Bangalore and took samples from residents at the camp. The team searched rooms, took urine samples from athletes and checked the medical supplies at the centre, according to the Press Trust of India news agency. The raids were also conducted last week at the National Institute of Sports in Patiala in northwest India, where some of the female runners who tested positive had been training.
