Oscar Pistorius, the double amputee who made history by competing in the Olympic Games this summer, has been arrested and charged with the murder of his girlfriend, Reeva Steenkamp in South Africa. 

Steenkamp, a model who spoke out on Twitter against rape and abuse of women, was shot four times in the predawn hours in the home, in a gated community in the capital, Pretoria, police said.

Hours later after undergoing police questioning, Pistorius left a police station accompanied by officers. He looked down as photographers snapped pictures, the hood on his gray workout jacket pulled up, covering most of his face. His court hearing was originally scheduled for Thursday afternoon but has been postponed until Friday to give forensics investigators time to carry out their work, said Medupe Simasiku, a spokesman for the prosecution.

Authorities said there had been "previous incidents" at Pistorius' home but that any statement by them about what happened would be irresponsible and premature.

Pistorius became a national -- and international star -- by becoming the first double amputee to compete in Olympic track. Nicknamed the "Blade Runner," perhaps no athlete created as much buzz in London. 

Steenkamp, 30, was one of FHM's 100 Sexiest Women and an outspoken advocate in the fight against women's violence.
