Track and field king Usain Bolt expressed shock at the developments in world track and field.
On Thursday, a report published and presented by an independent commission of the World Anti-Doping Agency (WADA), claimed former IAAF president Lamine Diack was responsible for corrupt schemes in regard to doping in Russia.
The 89-page report named Russia "a doping haven" and said the IAAF had inadequate governance in place to prevent the corruption that occurred when athletes paid bribes to cover up positive doping tests.
According to Bolt “when I heard it was quite shocking for me to hear that because as far as I was concerned I think they were doing a good job to clean up the sport,” Bolt told Reuters in Kingston.
“So for me to hear something like this was quite shocking and you feel let down as an athlete to be wanting to actually help clean up the sport, and then something like this to come up about the body.
The IOC said it "will continue to work closely with the new leadership of the IAAF" to protect clean athletes.
IAAF President Sebastian Coe was in attendance at the press conference and French prosecutors too as they are also investigating.
“It’s kind of a letdown, so hopefully there’s no such thing, but we’ll see what happen (with the investigations),” added Bolt.
