Weightlifters from five State units -- Services Sports Control Board, Delhi, Manipur, Haryana and Punjab -- had earlier tested positive for banned substances across different competitions and hence are being stopped from participating in the upcoming tournament, to be held in Patiala from December 24 to 29.
"We have banned Services Sports Control Board, Delhi, Manipur, Haryana and Punjab from taking part in the national championship because the weightlifters from these State units had earlier tested positive for doping," IWF secretary general Sahdev Yadav told PTI.
In April this year, the National Anti-Doping Agency (NADA) had caught 21 weightlifters in five championships for testing positive for banned substances.
Out of those 21, 16 were from Delhi, Punjab and Haryana, who were caught at the National Youth and Junior Weightlifting Championships, held in Yamunanagar in January.
