BBC News with Jonathan Izard.__________________________________________________________________________________________ .Mr. Pistorius, the Paralympics sprint champion, denies murder saying he shot his girlfriend Reeva Steenkamp thinking she was an intruder at his home. Andrew Harding reports from Pretoria.Detective Hilton Botha was back in the spot light today for all the wrong reasons, the man who yesterday insisted Oscar Pistorius was a murderer and a flight risk was dramatically dropped from the investigation. National Police Commissioner Riah Phiyega said Mr. Botha had been charged with attempted murder for a shooting incident in 2011. For that reason, I have decided to assign this very important matter, this very important investigation under the leadership and stewardship of the divisional commissioner of detective services Lieutenant-General Moonoo. A decision on whether to grant Mr. Pistorius bail is expected on Friday.
