Police say they found two boxes of testosterone and needles in the bedroom of Oscar Pistorius, the Olympian who has been charged with premeditated murder in the shooting death of his girlfriend, Reeva Steenkamp.

Detective Hilton Botha made the revelation today in testimony at the bail hearing for the athlete.

The discovery raises the possibility that the double-amputee Olympian and Paralympian might have been using performance-enhancing substances.

Pistorius became the first Paralympian runner to compete at the Olympic Games in London last year.

Pistorius, 26, has insisted he shot the 29-year-old Steenkamp by mistake, fearing there was an intruder in his gated and guarded luxury complex in the capital, Pretoria.
