Police investigating the death of the model girlfriend of Oscar Pistorius are reportedly studying the possibility that the South African sprinter killed her in a steroid-induced fit of rage.
Blood samples taken from the Olympian are being tested for drugs after steroids were allegedly found in the luxury Pretoria home where the 26-year-old is accused of murdering his girlfriend of three months Reeva Steenkamp, The Sun reports.
"Steroid drugs were found at Pistorius’s home together with evidence of heavy drinking. That’s why police have specifically ordered that he be tested for steroids," a source close to the investigation has revealed.
The model was shot four times in the head and body and police now reportedly believe she was initially struck as she tried to flee the bedroom.
An iPad believed to have belonged to Steenkamp was also found in the room and police are now scouring it for clues.
The news comes amid claims that Pistorius nearly shot a friend at an upmarket restaurant recently when the pistol he was looking at accidentally went off.
Pistorius was looking at a friend's gun at a restaurant in Johannesburg when the firearm discharged accidentally, Kevin Lerena told the Afrikaans-language Beeld newspaper.
"I had quite a fright, because the bullet hit the ground centimetres from my foot," said Lerena, a professional boxer, who described the incident as "a freak accident."
"For some reason it got caught on his trousers, flipped the safety pin and a shot went off. I wouldn't say he was negligent. Days afterwards he was still apologising."
"The revolver belonged to one of his friends... he wanted to have a look at it."
The restaurant manager heard a loud bang, but Oscar and his friends denied anything had happened, he told the newspaper.
The incident occurred less than a month before the star athlete was charged with murder after his girlfriend was shot dead at his home in the early hours of Valentine's Day.
His family has strongly denied that he intentionally killed his girlfriend and the sprinter is due to appear in court today at a bail hearing.
