(CNN) -- Last year he shocked South Africa's Oscar Pistorius to win over 200m at the Paralympics and Sunday Brazil's Alan Oliveira returned to London's Olympic Stadium to prove he is the fastest amputee sprinter in the world. The 20-year-old Oliveira stormed to victory over 100m in 10.57 seconds, shattering his own recently set record for his T43 class. It left him well clear of American Richard Browne, who finished second in a mixed class race, in 10.75 seconds, itself a world record for a single amputee in the T44 class. Britain's Jonnie Peacock, who won 100m gold in his class before his home crowd last year, finished third in a career-best 10.84 seconds.
