Amusan set a new world record for the women’s 100m hurdles after clocking 12.12 seconds at last year’s World Athletics Championships.

Meanwhile, the 26-year-old athlete has vowed to clear herself of the charges before the world championships next month.

“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,” she said.

“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 favour and that I will be competing at the World Championships in August.”

Meanwhile, Amusan won the 100 metres hurdles at the Silesia Diamond League in Poland on Sunday, setting a new meeting record of 12.34 seconds.
