Pistorius 'Fired Gun In Car And Cheated On Ex'
An ex-girlfriend of Oscar Pistorius wept as she told the court how the athlete cheated on her with Reeva Steenkamp.
It was also confirmed on Friday that the Paralympian would take the stand during the trial.
Samantha Taylor told how Pistorius once shot a bullet through a car sunroof, and on another occasion waved his weapon at a vehicle which he thought was following him.
:: Sky News' live coverage of the trial is under way, and a special highlights programme will be broadcast every weekday at 9.30pm.
Proceedings were halted twice as Ms Taylor had to compose herself during a drama-packed morning at the Pretoria court.
The evidence was heard shortly before a Pistorius family spokesperson confirmed for the first time that the athlete will, at some point, give evidence at the trial.
In another development, a security guard at the star's estate said Pistorius told him that "everything is fine" shortly after shots were reported.
"Mr Pistorius said to me 'security, everything is fine'," Pieter Baba told the court on Friday afternoon.
"That's when I realised that Mr Pistorius was crying," he added.
Earlier, Ms Taylor told how Pistorius nearly always carried a gun and recalled one night when she was awoken by the athlete who feared an intruder in the house.
The court was told how Pistorius grabbed his gun, got out of bed and went to investigate.
Ms Taylor also described occasions when Pistorius screamed at her "out of anger" and said he was often on his mobile phone when they were in bed together.
She described another time when the athlete became angry when police stopped a car he was travelling in.
The court heard that about 15 minutes after being stopped he fired his gun out of the sunroof - to "irritate the police", laughing after doing so.
He had earlier joked with the driver of the car about shooting "a robot" - South African slang for a traffic light.
On another occasion Pistorius was followed by a white Mercedes car, the court heard.
Ms Taylor said that Pistorius leapt out of his car as he approached the security gates of his home and waved his gun at the car, which drove off.
The court was told how Ms Taylor normally spent four nights a week at Pistorius' home.
She wept, and the court was adjourned twice, as she said how "upset" she was about the couple's break-up and the fact that she had been cheated on.
Earlier, radiologist Johan Stipp finished giving his evidence and was questioned by defence lawyer Barry Roux.
He had described on Thursday how Pistorius knelt at Ms Steenkamp's side and struggled in vain to help her breathe by holding two fingers in her clenched mouth.
Mr Stipp said he went to Pistorius' home after hearing shots fired on the night Ms Steenkamp was killed and found "a lady lying on her back".
"I also noticed a man kneeling on her side, on the left side. I remember the first thing he said when I got there was 'I shot her, I thought she was an intruder. I shot her,'" Mr Stipp told the court.
He said he did not recognise Pistorius, and described how he tried in vain to resuscitate Ms Steenkamp.
He said Pistorius was "crying all the time" and praying that she would not die.
On top of the premeditated murder allegation, Pistorius faces a charge of illegally possessing ammunition and two further counts related to shooting a gun in public in two separate incidents before the killing.
He denies all the charges against him and maintains he shot Ms Steenkamp after mistaking her for an intruder.
The athlete could face 25 years in jail if he is found guilty by Judge Thokozile Masipa. South Africa does not have trials by jury.
The trial has been adjourned until Monday.
