Oscar Pistorius got his first gold medal of the 2012 Paralympics by leading his South African T42-46 4x100m relay team's victory.
The South African team won on Wednesday evening in a new world record time of 41.87 seconds.
Pistorius, the defending 100m champion, also qualified with the second quickest time for Thursday's T44 final.
A few days earlier the 'blade-runner' missed out on a gold medal in the T44 200m.
He then complained about the length of his opponent's blades, claiming they were "not running in a fair race".
But the South African later apologised for making his outburst straight after the race.
