Oscar Pistorius walked out of court on Friday - free at least for now - after a South African magistrate released him on bail, capping four days of often startling testimony that foreshadowed a dramatic trial in the Valentine's Day slaying of his girlfriend.

But as he was driven away, chased by photographers and cameramen, questions continued to hound the double-amputee Olympian about what actually happened the night he gunned down Reeva Steenkamp inside a locked bathroom in his home.

Pistorius is charged with premeditated murder, and even Chief Magistrate Desmond Nair expressed doubts about his story that he mistook the 29-year-old model for an intruder and fired out of fear.

"Why would (Pistorius) venture further into danger" by going into the bathroom at all? Nair asked.

Cries of "Yes!" went up from Pistorius' supporters when Nair announced his decision to a packed courtroom after a nearly two-hour explanation.

Nair set bail at 1 million rand ($113,000), with $11,300 in cash up front and proof that the rest is available. The 26-year-old track star was also ordered to hand over his passports, turn in any guns he owns and keep away from his upscale home in a gated community in Pretoria, which is now a crime scene.

He cannot leave the district of Pretoria without his probation officer's permission and is not allowed to consume drugs or alcohol. His next court appearance was set for June 4.

Earlier, Pistorius alternately wept and appeared solemn and composed, especially as Nair criticized police procedures in the case and as a judgment in the track star's favor appeared imminent. He showed no reaction as he was granted bail.

Pistorius left the courthouse in a silver Land Rover just over an hour after the bail conditions were set. The vehicle, tailed by motorcycles carrying television cameramen, later pulled into the home of Pistorius' uncle.
