Athletics secretary-general David Okeyo said in September 2008 that Muthuka returned a positive test in July 2008 after setting a Kenyan record of 50.2 seconds at the national championships. She broke the 24-year-old mark by 3.1 seconds.
Muthuka is the fourth female runner Athletics Kenya has banned for doping in the past five years. Okeyo said all the athletes who failed doping tests had unwittingly used medication containing banned substances.
"But ignorance is no defense," Okeyo said.
