Four top throwers from India have been caught in a premier national athletics meet that was also a qualifying event for the London Olympic Games.

This is less than a year after a major doping scandal rocked the women’s 4X400m relay team.

Discus throw winner Kirpal Singh and silver-medalist in hammer, Harvinder Singh Daggar, also tested positive for steroids and provisionally suspended while Anshu Rai tested positive for a stimulant and will face NADA panel hearing.
