A cricket bat covered with blood had been reportedly found at convicted Paralympic star Oscar Pistorius' home, following reports that his girlfriend Reeva Steenkamp's skull was crushed.
According to police sources, the bloodied bat was kept by the athlete behind his bedroom door to ward of intruders, the Mirror reports.
The paper added that the South African police are investigating whether the bat was used to kill Steenkamp, or whether she used the bat for the purpose of self-defence.
Blade Runner Pistorius, 26, was charged with murder after his model girlfriend was shot dead at his luxury home in Pretoria on Valentine's Day.
According to the paper, police are also testing the gold medallist's blood for steroids, amid speculation he may have experienced "roid rage", aggressive behaviour linked to taking large doses of performance enhancing drugs. (ANI)
