IAAF president Sebastian Coe called alleged bribery within athletics "abhorrent" yesterday after claims that predecessor Lamine Diack received more then 1 million ($1.65m) to cover up doping violations.
"That people in our sport have allegedly extorted money from athletes guilty of doping violations is abhorrent," said Coe in a statement.
It was the former double Olympic champion's first response to the sport's latest crisis. Coe, elected president in August, also denied that the governing body of athletics had been complacent in its handling of doping cases, as alleged by the Sunday Times and German broadcaster ARD.
Coe's comments came after French authorities this week placed former IAAF president Diack under formal investigation on suspicion of corruption and money laundering.
The 82-year-old Senegalese is alleged to have received bribes in 2011 to cover up positive doping tests of Russian athletes, the office of France's financial prosecutor said. One of Diack's sons and three other officials, two who held IAAF positions, have also been charged with ethical violations by the governing body.
