- Senegalese authorities have blankly refused to allow French judges question Papa Massata Diack as part of a corruption probe into his father, disgraced former IAAF chief Lamine Diack, judicial sources said. Both Papa Massata Diack and his 83-year-old father face charges in France over millions of dollars paid to cover up doping failures by Russian athletes. Lamine Diack is barred from leaving France, while Papa Massata Diack has been in hiding in Dakar where Senegalese authorities have refused to extradite him. A French judicial source told AFP that in addition to the arrest warrant, a formal rogatory international letter was sent to Dakar in May 2016 calling for his indictment. "The Senegalese authorities have indicated that they will not execute this request," the same source added.
