Jakarta: Turkmenistan’s freestyle wrestler Nazarov Rustem has become the first athlete at the Asian Games in Jakarta to fail a doping test, the Olympic Council of Asia (OCA) said on Friday.

Rustem, who was eliminated in the pre-quarterfinals of the 57kg class, had his results annulled after failing a pre-competition test on Aug. 17, it said.

‘His urine sample showed the presence of furosemide, which is a prohibited substance under ... the WADA prohibited List 2018,’ the OCA, which governs the Games, said.

At the 2014 Asian Games in Incheon, a total of five athletes tested positive for banned substances and were sent home.

South Korea’s Park Tae-hwan was later stripped of his swimming medals for failing a pre-Games test.
