Carl Pistorius, brother of Oscar Pistorius in court on culpable homicide charges

The brother of South African athletics star Oscar Pistorius has appeared in court over a motorcyclist's death in a road accident in 2008.

Carl Pistorius is charged with the culpable homicide of a 36-year-old woman, in a collision involving his vehicle near Johannesburg.

His lawyer says he is innocent.

In an unrelated case, Oscar Pistorius has been charged with the murder of his girlfriend, Reeva Steenkamp, last month - a charge he denies.

On Thursday, the Olympic and Paralympics star's lawyers are expected to challenge in court the bail conditions imposed on him.
