JOHANNESBURG, AP:

Two days before he was due to leave prison, Oscar Pistorius' early release was suddenly put on hold yesterday by South Africa's Department of Justice, which sent his case back to a parole board.

It was unclear when the board would be able to meet again, justice department spokesman Mthunzi Mhaga said, but it was unlikely a new decision could be made by tomorrow's initially planned release date.

Pistorius, the double-amputee Olympic runner, is serving a five-year sentence for manslaughter for killing girlfriend Reeva Steenkamp in 2013. He was eligible to be moved from jail to house arrest after serving one-sixth of that sentence, or 10 months, which is up tomorrow.

Yesterday would also have been Steenkamp's 32nd birthday, and her parents earlier held a beachside ceremony in their hometown of Port Elizabeth on South Africa's south coast.

In blocking Pistorius' release, the justice department said he was approved for home correctional supervision by parole officials in June, only eight months into his sentence. By law, he should have served 10 months of his sentence before his case could be reviewed, the department said.
