Drugs found in Oscar Pistorius' home in murder investigation

Police searching the home of South African Olympic sprinter Oscar Pistorius said that they found testosterone and needles in a dresser in his bedroom.

Investigating officer Hilton Botha said the substance -- banned by the International Olympic Committee -- was found by police investigating the killing of Pistorius's girlfriend Reeva Steenkamp.

Pistorius will also face an additional charge of possessing unlicensed ammunition

At a bail hearing, prosecutors say they found a box of special calibre rounds

They said Pistorius is not a licence-holder for that type of ammunition

The double-amputee is accused of murdering his girlfriend Reeva Steenkamp

Prosecutors added that a witness heard "non-stop shouting" coming from his home shortly before he shot his girlfriend four times.  

Pistorius has denied the murder charge

He told the court that he shot at his girlfriend through a locked bathroom door, mistakenly believing she was a burglar.
