"He was... very scared that he could be attacked," Roux put to State witness Samantha Taylor.

Paralympian Oscar Pistorius was scared of being attacked, his lawyer Barry Roux told the High Court in Pretoria on Friday.

"He was... very scared that he could be attacked," Roux put to State witness Samantha Taylor.

She replied: "Not necessarily... I don't think he was scared."

Roux then asked her about a day in April 2012 when she and Pistorius were pursued by a white C Class Mercedes.

"I recall it being a black BMW," she said.

She said when they arrived at Pistorius's gated complex in Pretoria, the athlete got out of his car with his gun and the car drove off.

She said neither of them was particularly scared at the time.

"He didn't seem very concerned," Taylor said.

She said when Pistorius walked on his stumps he had to balance against something.

Responding to Roux's statement that Pistorius kept his gun under his bed, she said he either kept it on the floor next to his bed or on his bedside table.

Pistorius is accused of the murder of model and law graduate Reeva Steenkamp. He is also charged with illegal possession of a firearm and ammunition, and two counts of discharging a firearm in public.

He allegedly fired a shot from a Glock pistol under a table at a Johannesburg restaurant in January 2013.

In September 2010 he allegedly shot through the open sunroof of a car with his 9mm pistol while driving with friends in Modderfontein.
