Two athletes, who are in contention for the Olympic Games, have failed dope tests conducted at the Indian Grand Prix in Patiala last month, the National Anti Doping Agency's Director General Navin Agarwal revealed on Saturday.

It is understood that one of the athletes is a high profile female quarter-miler, who has won multiple gold medals in the 4x400m relay event and was supposed to be a part of the Tokyo-bound team. However, neither NADA nor the Athletics Federation of India have divulged any names.
