South African prison officials say Oscar Pistorius spent his first night in a single cell in the hospital wing of a prison in the capital, Pretoria.

Prison commissioner Zebilon Monama told the South African Press Association that Pistorius seemed confused and tired when he entered the Kgosi Mampuru facility and was visited by the jail's psychologist and chaplain last evening.

He said Pistorius shares the hospital ward with eight other prisoners with disabilities.

The athlete had a medical examination before being locked in his cell.

The hospital wing has routine 24-hour observation with two nurses on duty. South Africa's department of correctional services says the country's prisons house an average of 128 disabled prisoners each year, less than 1 percent of the country's total 157,000 prison population.
