Indian athlete Jithin Paul has been banned for four years after National Anti Doping Agency (NADA) found that the 400 metre hurdler was in possession of a prohibited substance called meldonium.
With this ban, Paul becomes first Indian athlete to be sanctioned for such an offence.
Paul is a 400m hurdles National Open champion and a 2016 South Asian Games silver medallist.
NADA, in an official statement, said, "The panel concludes that athlete Mr Jithin Paul was in possession of prohibited substance i.e. meldonium and violated the Article 2.6 of the Anti Doping rules of NADA 2015."
The statement further notified that the athlete has been found in possession of meldonium in his room at National Institute of Sports, Patiala, Punjab, during the search by NADA in April 2017.
The Anti Doping agency clarified that Paul had no reasonable justification of the prohibited substance in his room.
Since January 2016, meldonium has been on the World Anti-Doping Agency (WADA) list of substances banned from use by athletes because of evidence of its use by athletes with the intention of enhancing performance.
On March 7, 2016, former world number one tennis player Maria Sharapova was handed a 15-month ban after she tested positive for meldonium in Australia.
