Women’s 100m hurdles world record-holder, Tobi Amusan, in the early hours of Wednesday, confirmed that she has been charged with an alleged anti-doping rule violation.

Amusan also promised to resolve the charges against her before this year’s competition, set to be held next month in Budapest.

The 26-year-old Nigerian athlete disclosed this in a post via her Instagram account.

She said, “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 athelete and I am regularly tested by the AIU” she wrote.

The latest development has now cast doubt on Amusan’s participation in next month’s world championships. Amusan set the current world record for the women’s 100m hurdles of 12.12 seconds at last year’s World Athletics Championships.
