Josephine Onyia Nnkiruka (born 15 July 1986) is a track and field athlete who specializes in the 100 metres hurdles.
She changed nationality from Nigeria to Spain in April 2007, following in the footsteps of another hurdler Glory Alozie.
[2] She competed in the hurdles at the Summer Olympics and just missed the final after finishing fifth in the semi-finals.
However, she tested positive for methylhexaneamine at the 2008 Athletissima meeting and also clenbuterol at the World Athletics Final.
The CAS upheld the IAAF's appeal and Onyia was suspended for two years and her recent past results were annulled, effectively removing her of all her achievements as a senior athlete.
