PRETORIA, South Africa (AP) - The spokesman for the state prosecutor in the Oscar Pistorius case says there was an error in a detective's testimony when he identified a substance police found in the athlete's bedroom as testosterone.
Medupe Simasiku, a spokesman for South Africa's National Prosecution Agency, said it is too early to identify the substance as it is still undergoing laboratory tests.
Detective Warrant Officer Hilton Botha, the investigating officer, said earlier Wednesday in court that police found testosterone and needles in the bedroom of the Olympic athlete.
Simasiku said it is "not certain" what the substance is.
Pistorius' defense said the substance found was not a steroid or a banned substance but an herbal remedy.
Pistorius is charged with premeditated murder for the Feb. 14 shooting death of his girlfriend, Reeva Steenkamp.
