When we put that allegation to the coaches there was a look of shock to be honest because running on different size prostheses or swapping them for races is extremely difficult to do for an athlete.
There is no evidence that any athlete competed on different size running blades.
Unless the South Africans can come to us with some evidence that proves otherwise, it's something that we won't continue investigating.
South Africa has made an official complaint that athletes are switching the size of their running blades after Paralympic star Oscar Pistorius claimed longer prosthetics gave a rival an unfair advantage.
The International Paralympic Committee (IPC) received a letter yesterday morning alleging that athletes had changed the length of their blades, breaking competition rules.
As things stand, it is against the rules to swap blades mid-competition.
Staff spoke to coaches in the athletes' village yesterday but found no evidence to back the South African claims.
Oscar Pistorius has won a gold medal with his South African team mates in the 4x100 metres relay T42/T46. Pistorius was the fourth member of the team to run and he was chased down the home straight by rival Alan Fonteles Oliveira, who beat him in the T44 200 metres.
Pistorius complained moments after his defeat that athletes were changing the size of their blades.
Bethany Woodward has won a silver medal in the women's 200 metres T37. Jenny McLoughlin finished in fifth place.
