The son of former IAAF president Lamine Diack has been interrogated for more than seven hours by police in his native Senegal.
Papa Massata Diack, an ex-IAAF marketing consultant, is wanted for questioning by prosecutors in France in connection with the corruption scandal surrounding track and field's world governing body.
He was banned for life from the sport last month in a bribery and extortion case involving Russian doping.
Diack's lawyer Bamba Cisse said his client was summoned "for a fair hearing" on Wednesday at police headquarters in Dakar.
Diack arrived for questioning just after 4pm local time and left at midnight without commenting.
Senegalese authorities have not said if they are pursuing charges against Diack. He and his father are both under investigation in France for extorting bribes from athletes to cover up doping.
Interpol has issued a wanted notice for Papa Massata Diack. Senegal says it will not extradite him.
