Four athletes including javelin thrower Rohit Kumar, who participated in the just-concluded Asian Grand Prix series, have tested positive.
The others are hammer thrower Harvinder Singh Dagar and discus throwers Kripal Singh and Anshu Rai.
All were tested at the Federation Cup meet at Patiala from April 21 to 24. Kripal belongs to Punjab; the others are from Allahabad, Uttar Pradesh.
Kripal, Rohit and Dagar tested positive for steroids, while Rai tested positive for stimulant methylhexaneamine. The three steroid offenders have been provisionally suspended.
It was not immediately known whether the National Anti Doping Agency (NADA), which did not reveal the names of the athletes while announcing the ‘positive' tests on Tuesday, had intimated the Athletics Federation of India (AFI) in time for it to pull out Rohit Kumar from Monday's Asian Grand Prix in Thailand.
No prize money
If the charge is proved, Rohit will lose his third place prize money ($500) at the Asian Grand Prix meet at Kanchanaburi (71.07m), apart from his placing in the Federation Cup.
