Oscar Pistorius' father Henke has spoken about his son's arrest for the alleged murder of girlfriend Reeva Steenkamp, saying his son is "sad at the moment".
Police had previously been called to the home of Pistorius' due to incidents "of a domestic nature", and said they were extremely surprised over media reports that suggested the athlete had fired shots after mistakenly believing there was an intruder in the house.
"I don't know nothing. It will be extremely obnoxious and rude to speculate. I don't know the facts," Henke Pistorius told SABC radio news.
