THE brother of accused murderer Oscar Pistorius is himself facing a charge of culpable homicide, it has been revealed on a day in which reports also said that police found a herbal sexual stimulant in the star athlete's home. Carl Pistorius was charged over the death of a woman who died when her motorbike collided with his car outside Johannesburg in 2010, his lawyer Kenny Oldwage told the eNews Africa television channel. The elder brother of athlete Oscar Pistorius was supposed to have gone on trial for culpable homicide on Thursday - the day before the Olympian got bail, according to South African media reports. Carl Pistorius and lawyer Kenny Oldwage pictured outside Brooklyn police station, where Oscar Pistorius was being held, last week. Oscar Pistorius and his brother Carl were seen driving into the home of their uncle Arnold today in Waterkloof, a wealthy suburb of Pretoria, the nation's capital, where Oscar is now staying. Sex stimulant, not steroids, found in home Meanwhile, a South African newspaper reported that a substance found in Oscar Pistorius's home during a search by police investigating the killing of his girlfriend is a herbal sexual stimulant, a South African newspaper reported. The City Press newspaper said the remedy was a combination of vitamins and herbal cures partly derived from animal organs. Charges against Carl compound problems The problems surrounding his older brother Carl, 28, are the latest twist in a case that has transfixed South Africa and much of the world. The revelation of the culpable homicide charge immediately created a stir. It's also doubly sad because it's involved with Oscar and his brother and all the family - so they have double sort of trouble. So, not good," said Johannesburg resident Jim Plester. Carl Pistorius's trial was pushed back a month, but the specific date is not known. The Pistorius family has yet to react to the accusations that Carl is facing. The latest developments comes just days after Hilton Botha, the lead detective investigating the Oscar Pistorius murder case, was dropped after it emerged he was facing seven attempted murder charges over a shooting incident in 2011. Along with his sister Aimee and father Henke, Carl Pistorius has been a strong source of comfort and support to his Paralympian brother, attending last week's bail hearings.
