The investigating officer in the Oscar Pistorius murder case has revealed that two bottles of testosterone were found in the Paralymic champion's home, a court has heard.

Detective Hilton Botha, who has been giving evidence on the second day of the double amputee's bail hearing at Pretoria Magistrates' Court, has revealed that a substance that he believed to be testosterone and needles were found on the premises following the death of Pistorius's girlfriend Reeva Steenkamp, who was shot dead through a bathroom door.

The defence, however, claiming that the bottles found were not testosterone, but a herbal remedy.

The 26-year-old athlete has been charged with the premeditated murder of the 29-year-old model, who was cremated in a private ceremony yesterday.

The prosecution told the court today that they had a witness statement claiming "non-stop fighting" could be heard from Pistorius's home for an hour on the morning of Steenkamp's death.

The court has ruled the charge as a schedule six offence, which damages the South African native's chances of achieving bail.

Pistorius has denied murder and revealed in his affidavit yesterday that he mistook Steenkamp for an intruder.
