The pictures, taken in the garage of his Pretoria home on the night Reeva Steenkamp was shot dead, also show the Paralympic athlete with blood on his left arm.

Former police Colonel Schoombie van Rensburg told the court in Pretoria that he arrived at the home of Pistorius around 30 to 40 minutes after he shooting.

He said he found the athlete pacing up and down the kitchen and described his state as "very emotional".

"I warned him of his rights," said van Rensburg.

"I said to him I wasn't arresting him at that stage...I requested him to remain present at all times at the scene."

More pictures showing the trail of blood inside the house were shown, including the toilet in which three bullets struck 29-year-old Steenkamp.

Earlier, van Rensburg said a ballistics expert had handled the gun which fired the fatal bullets without wearing gloves.

"I was very angry," he said.

"I asked him, 'what are you doing?'

"I couldn't believe it."

He also said a watch inside Pistorius' bedroom had gone missing.

The watch was inside a case which had been marked by blood.

Van Rensburg said officers were searched but the watch was never recovered.

Defence lawyer Barry Roux questioned the way evidence was gathered by detectives, arguing the scene was contaminated by police.

The trial is due to resume on Monday (March 17) - the 11th day of proceedings - with the prosecution continuing to lay down its case.

Pistorius, 27, who shot his girlfriend dead on February 14 - Valentines's Day - last year, denies premeditated murder.
