Oscar Pistorius case: Top detective brought in

South Africa's top detective is to take over the Oscar Pistorius inquiry amid attempted murder accusations against current lead officer Hilton Botha.

Detective Botha was removed pending the result of an investigation into seven counts of attempted murder.

National police commissioner Mangwashi Phiyega announced the change after a third day of testimony at Mr Pistorius's bail hearing.

Mr Pistorius, 26, denies murdering his girlfriend Reeva Steenkamp, 29.
