PRETORIA, South Africa — Oscar Pistorius, the double-amputee sprinter dubbed the Blade Runner, was charged in the Valentine's Day slaying of his girlfriend at his upscale home in South Africa, a shocking twist to one of the feel-good stories of last summer's Olympics.

Pistorius buried his face in the hood of his workout jacket as officers escorted him from a police station after his arrest in the shooting death of 30-year-old model Reeva Steenkamp.

Police said she was shot four times in the pre-dawn hours at Pistorius' villa in a gated community in the capital. Officers found a 9 mm pistol inside the home and arrested Pistorius on murder charges.

Police also said they had received calls in the past about domestic altercations at the home of the 26-year-old athlete.

Local columnists and commentators have called for the team to change its name in recent days.
