Former IAAF president Lamine Diack is being investigated in relation to allegations that he helped to cover up doping cases.

The 82-year-old is suspected of taking money from Russia to sweep over positive drugs tests.

His advisor, Habib Cisse, is also being investigated.

Sebastian Coe succeeded the Senegalese as IAAF president in August, bringing an end to Diack’s 16-year reign.

A statement from the IAAF confirmed that French police visited their offices on Tuesday to conduct interviews.

"The IAAF confirms that, emanating from separate ongoing investigations by WADA’s independent commission and the IAAF’s own independent Ethics Commission into allegations surrounding its anti-doping rules and regulations, a French police investigation has now commenced," a statement read.

"The IAAF is fully cooperating with all investigations as it has been from the beginning of the process.

"As part of the French investigation, police visited the IAAF HQ offices yesterday to carry out interviews and to access documentation.

"The IAAF will make no further comment at this time."
