NAIROBI, Kenya (AP) -- Kenyan track authorities are investigating claims of increased doping among its famed distance runners and has asked the World Anti-Doping Agency and police for help.
Athletics Kenya chairman Isaiah Kiplagat told The Associated Press on Thursday the national federation was looking into allegations by a German reporter and an athlete that performance-enhancing substances were being made available to runners by people posing as doctors.
WADA said it is aware of the allegations, has communicated with "the relevant authorities" and would "monitor the inquiry."
Kiplagat insisted Kenyan runners were "very clean" but his federation wanted to know the cause of the allegations.
Four Kenyans have been sanctioned this year by track and field's governing body. Others have reportedly failed tests, including one athlete who said many of his compatriots were doping.
