The World Anti-Doping Authority (WADA) has confirmed it passed information onto French police that saw the headquarters of the International Association of Athletics Federations (IAAF) raided on Wednesday.
WADA has been investigating serious doping allegations within athletics since January and information collected by its Independent Commission during this time has led to the latest developments in Monaco.
Earlier on Wednesday it emerged that former IAAF president Lamine Diack is reportedly being investigated by French authorities amid allegations of corruption and money laundering.
Diack, who has since been replaced by Seb Coe, is also being accused of covering up positive drugs tests from Russian athletes.
“WADA is aware of the ongoing criminal investigations relating to sport officials and allegations of corruption and money-laundering, as announced by the French authorities earlier today,” the authority said in a statement.
“These investigations are a result of information passed on by WADA’s Independent Commission (IC) to the relevant authorities.
“WADA will make no further comment at this time.”
