Oscar Pistorius will face no disciplinary action over his outburst following defeat in the men's 200 metres final, Paralympic organisers said on Tuesday.

Moments after losing to Brazil's Alan Oliveira on Sunday, his first 200m defeat in nine years, Pistorius used a post-race interview to question the legitimacy of his defeat.

Pistorius, dubbed the "Blade Runner", suggested that his opponent's prosthetics were too long which had artificially lengthened his stride, giving him an unfair advantage.

"There will be no disciplinary action against Oscar for his comments," International Paralympic Committee (IPC) director of communications Craig Spence said on Tuesday.

Pistorius apologised for the timing of his comments in a statement on Monday, but maintained there was still a fundamental issue about the length of athletes' prosthetics that needed to be addressed.

Pistorius met with Paralympic officials in the immediate aftermath of his defeat when it was decided a further meeting would take place to discuss his concerns.

"We decided we needed to go through the official channels rather than just sending an informal text message saying let's meet," Spence added.

"So we are waiting for the national Paralympic Committee of South Africa to go through the relevant channels and contact the IPC and then a meeting will be set up."

Pistorius, who was defending his 100m, 200m and 400m titles, streaked into an early lead and was almost 10 metres ahead as the athletes came into the home straight but the Brazilian launched a stunning fightback and surged to victory.

IPC rules governing the length of prosthetics are determined by a complicated formula that involves measuring from the chest to the amputated limb and the arm span.

This is converted into a height prediction and a maximal height is used to assess the length of prosthetics.

Immediately after the race, the IPC confirmed that Oliveira's blades fell within the legal limits.

Pistorius continues his Paralympic campaign on Wednesday in the 100m heats, with the 400m and 4x400m relay to follow later in the week.

A 30-year-old woman was found fatally shot in the upscale Pretoria home belonging to South African Olympian Oscar Pistorius, police said Thursday.

Police said they have arrested a 26-year-old man -- the same age as Pistorius -- in connection with the shooting and that he will appear in Pretoria magistrate court sometime Thursday.

Pistorius, nicknamed the "Blade Runner," made history when he became the first Paralympian to compete in the able-bodied Olympics last year.

Several South African media outlets reported that the woman was mistaken for an intruder. Police Brig. Denise Beukes said she was aware of the reports, but could not confirm them.

South Africa has a high crime rate, and it's not unusual for homeowners to keep weapons to protect themselves from intruders.

Pistorius, a double-amputee, ran with the aid of prosthetic limbs during the London Olympics last year, the first Paralympian to compete in the able-bodied Olympics.

The runner's legs were amputated below the knee when he was a toddler because of a bone defect. He runs on special carbon fiber blades, hence the nickname.

While he failed to win a medal in the Olympics, his presence on the track was lauded as an example of victory over adversity and a lesson in dedication to a goal.
