London - Brazil's Alan Oliveira smashed the T43 100 metres world record with a time of 10.57 seconds at the Paralympic Anniversary Games in London on Sunday.
Double amputee Oliveira defeated Oscar Pistorius to win a gold medal in the 200m at the London Paralympics last year and 12 months later he has enjoyed more glory in the Olympic Stadium.
The 20-year-old became the world's fastest amputee sprinter by running a record 10.77s for the 100m in Berlin last month.
And Oliveira, who only finished seventh in the 100m Olympic final last year, was in blistering form on Sunday as he shattered his own record.
American Richard Browne finished second in the mixed-class race in a T44 world record, for single amputees, of 10.75s, with Britain's Jonnie Peacock third in a career best 10.84s.
"I can't express how happy I am," Oliveira said. "Richard Browne and Jonnie are very fast, I know that.
"I just wanted to run for 10 seconds and that's what I did."
Meanwhile, Browne believes the success of athletes like Oliveira means it is only a matter of time before more amputees compete in the Olympics rather than Paralympics.
Pistorius had to win a lengthy legal battle with the IAAF, going through the Court of Arbitration for Sport, for the right to compete alongside able-bodied athletes in the London Olympics.
His Cheetah blades were subject to scientific tests to determine whether they gave him an advantage or not.
And Browne expects several attempts to follow Pistorius's example before the Rio Olympics in 2016.
"Oscar (Pistorius) broke down so many doors for us and we all owe him gratitude because he showed the world it's not just crippled people trying to run," Browne said.
"We will break the able-bodied barrier, to the point where we have it all together.
"There's going to be more than one in the able-bodied Olympics by 2016.
"I talk to a lot of the able-bodied athletes and they accept us with open arms.
"The IAAF just need to get their rules ready, that's all I'm saying."
