The Athletics Integrity Unit has confirmed a provisional suspension against Kenyan long-distance runner Salome Jerono Biwott for violation of the IAAF Anti-Doping Rules.
The 36-year-old athlete has been tested positive to presence of a prohibited substance known as Norandrosterone.
Biwott was first hit with a two-year ban in 2013 when she failed a drugs test after winning the 2012 Standard Chartered Nairobi Marathon. This year, she came second at Sao Paulo International Marathon in 2 hours, 37 minutes and 33 seconds on April 7.
She is likely to get a four-year ban if found guilty, four years after completing the first doping ban.
Biwott becomes the fourth Kenyan to be suspended for doping within two months after World Half Marathon record holder Abraham Kiptum, 2017 World Champions 5,000m representative Cyrus Rutto and Felix Kirwa were sanctioned.
It now brings to 10 the number of Kenyan elite athletes that AIU has either suspended or banned for doping offenses.
A Provisional Suspension is when an Athlete or other Person is suspended temporarily from participating in any competition or activity in Athletics prior to a final decision at a hearing conducted under the IAAF Anti-Doping Rules or the Integrity Code of Conduct.
