Ammon News - (BBC) - Brazilian Alan Oliveira has become the world's fastest amputee after breaking Oscar Pistorius's 100m T43 record with a time of 10.77 seconds.

The 20-year-old set the record at the IPC Athletics Grand Prix in Berlin.

His time is 0.14 seconds faster than the previous record of 10.91, which was set by South African Pistorius in April 2007 and equalled by Blake Leeper of the United States in July.

It is also 0.08 seconds faster than the 100m T44 record held by Jonnie Peacock.

Oliveira could only finish seventh in the 100m T44 final at the Olympic Stadium in September as the 20-year-old Briton took gold.

The pair will face each other again at July's IPC World Championships in Lyon, with American Richard Browne, who last weekend unofficially equalled Peacock's best of 10.85 seconds, also set to line up against them.

Oliveira beat Oscar Pistorius to gold in the T43/44 200m at London 2012, which prompted the South African athlete to complain about the length of his opponent's blades.

The T43 category includes double below-the-knee amputees and other athletes with impairments deemed equivalent, while the T44 category is for those athletes who are single below-the-knee amputees and equivalent impairments.
