World champion Tobi Amusan has been charged by the Athletics Integrity Unit with an alleged doping violation as regard missing three whereabouts tests.

The women’s 100m hurdles World record holder also asked that her privacy be respected be respected.

“Today the Athletics Integrity Unit (AIU) has charged me with an alleged rule violation for having 3 missed tests in 12 months.

“I intend to fight this charge and will have my case decided by a tribunal of 3 arbitrators before the start of next month’s World Championships. I am a CLEAN ATHLETE, and I am regularly; (maybe more than the usual) tested by the AIU – I was tested within days of my third “missed test.” I have FAITH that this will be resolved in my favor and that I will be competing at the World Championships in August. In the meantime, I ask that the media respect my privacy while I address these allegations in my upcoming arbitration,” Amusan wrote.

Under World Athletics Anti-Doping Rules, the sanction for three ‘whereabouts’ failures is two years’ ineligibility, subject to a reduction to a minimum of one year depending on an athlete’s degree of fault.
