Photographs of a bare-chested Oscar Pistorius taken in the aftermath of his girlfriend Reeva Steenkamp's death have been shown in court. In one image, the athlete was seen drenched in blood from the waist down, his prosthetic legs splattered with red fluid.

Another picture showed the South African clenching his hands, with blood smeared across his left arm.

The court also heard how the door of Pistorius' bathroom was dismantled, stashed in body bags and stored in former police colonel Schoombie van Rensburg's office where it could be guarded by security.

The door was propped up against a desk for several days, although Mr. van Rensburg, who was among the officers sent to Pistorius' home, insists it was not tampered with.

Asked by defence lawyer Barry Roux what he found when he arrived at the house, Mr. van Rensburg recalled seeing a pellet gun and an empty cartridge as he made his way towards the bedroom.

He said he followed a "blood trail" to the bathroom, where two mobile phones and a discarded tissue were found. A gun holster and a magazine discovered on a bedside table were seized, along with rounds of ammunition, he added.

Mr. van Rensburg repeatedly denied tampering with evidence at the scene, although he admitted he was unable to see his colleague when he left the house temporarily.

The evidence comes after further graphic evidence was shown to the court in Pretoria on Thursday.

Pistorius (27) vomited as images of blood stains on floors, walls, stairs and chairs in his home were displayed. Photos of Ms. Steenkamp's body, including close-ups of her various injuries, were also shown accidentally.

Pistorius is charged with premeditated murder, as well as illegally possessing ammunition and two further counts related to shooting a gun in public in two separate incidents before the killing.

He denies the charges against him and says he shot Ms. Steenkamp (29) by mistake after mistaking her for an intruder.
