South Africa's Department of Justice says it is putting Oscar Pistorius's release from prison on hold until his case is reviewed again by a parole board.

Department spokesman Mthunzi Mhaga says Pistorius's release will have to be reviewed again because he was approved to be moved to house arrest too early.

Mr Mthunzi saids Pistorius should have served 10 months of his sentence before being considered for release. He was approved for parole in June, eight months into his sentence.

Pistorius was due to be moved to house arrest on Friday after serving 10 months of his five-year sentence for manslaughter for killing girlfriend Reeva Steenkamp in 2013.

Mr Mhaga did not say when the parole board would meet to consider Pistorius for release from jail.
