Prosecutors attempt to send disgraced star back to prison

South African state prosecutors were due on Tuesday to argue in court for Oscar Pistorius to be convicted of murder and sent back to prison, two weeks after he was released on house arrest.

The disgraced Paralympic sprinter was found guilty last year of culpable homicide - a charge equivalent to manslaughter - after shooting dead his girlfriend, Reeva Steenkamp, on Feb 14, 2013.

At the Supreme Court of Appeal in Bloemfontein, state prosecutors were to try to convince judges that Pistorius should be found guilty of murder and sentenced to a minimum of 15 years in prison.
