Olympic athlete Oscar Pistorius was taken into custody and was expected to appear in court Thursday, Feb 14, after a 30-year-old woman who was believed to be his girlfriend was shot dead at his home in South Africa's capital, Pretoria, according to The Associated Press.

Police Lt. Col. Katlego Mogale told the AP that officers received a call in the early hours of the morning that there had been a shooting at the double-amputee runner's home in a gated housing complex.

Mogale said when police arrived they found paramedics trying to revive the woman, who had been shot an unspecified number of times. Mogale, who was speaking to the AP from the scene, said the woman died at the house.

Officers found a 9 mm pistol at Pistorius' house and Mogale said the 26-year-old Pistorius is expected to appear in court later on Thursday.

Police have not released the name of the woman, but the publicist for Reeva Steenkamp, Pistorius' girlfriend, told Sky News that Steenkamp had died. Tributes to Steenkamp, a model, poured onto social media sites.

Many South African media outlets had reported that the dead woman was Pistorius' girlfriend Steenkamp and that he may have mistaken her for a burglar and shot her, but police did not clarify the dead woman's relationship to Pistorius. Mogale said the victim's family had not yet identified the body.

It was reported that the woman may have been trying to surprise Pistorius for Valentine's Day and he thought she was an intruder breaking into his home. The shooting prompted discussions on talk radio shows about the country's gun control laws.

Pistorius made history in London last year when he became the first double-amputee track athlete to compete in the Olympic Games. He is one of South Africa's and the world's most famous sportsmen.
