New Delhi, Sep 11: Priyanka Panwar, a 2014 Asian Games women's relay gold medallist, has been slapped an eight-year ban for failing a dope test for the second time, sources close to the development here said on Monday. Panwar had tested positive for the stimulant mephentermine during the Inter-State Athletics Championships held at Hyderabad from June 28 to July 2, last year. She was under provisional suspension since then. Panwar was selected for the Rio-bound 4x400m relay team, but was later dropped. She was replaced by Ashwini Akkunji. National Anti Doping Agency's (NADA) disciplinary panel has handed out the verdict on the 29-year-old Uttar Pradesh athlete, said the sources who wished to remain unidentified. The NADA code stipulates that athletes caught for a second anti-doping rule violation get a sanction ranging from eight years to a maximum life-time ban. The athlete's national and international medals stand forfeited with immediate effect. Panwar had failed a dope test in 2011 for an anabolic steroid. She was among six top women quarter-milers who had failed dope tests. All the six were banned for two years. After she returned from the two-year ban in 2013, she was selected for the national camp, and included in the Incheon Asian Games relay squad.
