PRETORIA - Oscar Pistorius will spend the night behind bars and is expected to appear in a Pretoria court on a murder charge on Friday.
The Paralympian was arrested in the early hours of Thursday morning after shooting his girlfriend Reeva Steenkamp at his Silver Woods Estate home in Pretoria.
Pistorius reportedly claimed he fired his gun after thinking an intruder had broken into his house.
Police spokesperson Denise Beukes said there was no evidence to suggest a break-in.
“There have been no reports of forced entry or persons in the property who were not supposed to be there.”
Beukes also said witnesses were being interviewed about hearing a commotion at the time of the shooting.
She said there had been previous reports of problems at the house.
“I am not going to elaborate but there have been previous allegations of a domestic nature.”
Beukes said the motive remained under investigation.
“The only two people were the residents and the deceased. The number of shots fired is also part of the investigation.”
Close family friend Samantha Sutton, who is with the Steenkamp's at their Port Elizabeth home, said police broke the news to the model's mother on Thursday morning.
“The detective phoned in at about 7.30am and she was extremely hysterical and she called me in.”
The family has not released a statement on the matter as yet.
Meanwhile, Nike South Africa said it would allow the official police process to be finalised before taking any decisions about its sponsorship of Pistorius.
The so-called Blade Runner is the face of several international brands including Oakley sunglasses and Thierry Mugler fragrances.
Nike extended its deepest sympathy and condolences to Steenkamp's family.
The sports brand's Seruscka Naidoo said, "This is a very tragic incident and it is a police matter."
