PRETORIA - Prosecutor Gerrie Nel has told the High Court in Pretoria the State will lead evidence which will show convicted murderer Oscar Pistorius has been untruthful to his psychologist.

This is among the submissions heard on day one of sentencing proceedings during the testimony given by the defence team's first witness, Doctor Jonathan Scholtz.

LISTEN: Prosecution argues psychologist is biased.

Pistorius is being sentenced as a murderer for the 2013 shooting of his girlfriend Reeva Steenkamp.

Nel challenged doctor Scholtz's claim that the athlete was confined to his cell for most of the day.

"We lead evidence that Mr Pistorius was not confined to his cell what would you say about that?"

"He explained to me that it wasn't everyday all the time, there were instances where he was allowed more freedom," the doctor responded.

He further challenged the claim that Pistorius saw an inmate who had hanged himself after being raped.

"People were walking past this body even moving it to the side to get past for quite a period of time and he saw the person hanging."

"That did not happen." Nel said.

The defence is expected to call its second and final witness tomorrow.
