Oscar Pistorius hurt in fight over prison phone

Jailed South African track star Oscar Pistorius suffered a bruise in a fight with another inmate over the use of a phone in prison where he is serving a sentence for murdering his girlfriend, a prison spokesman has confirmed.

Fellow prisoners were angered by a long phone call he made and it led to a fight, local media reported.

"Oscar sustained a minor bruise. It was so minor it didn't need any form of treatment," said Singabakho Nxumalo, a spokesman at the Department of Correctional Services.

He said authorities were investigating, with the incident taking place last Wednesday.

Pistorius won six Paralympic gold medals and was known as the Blade Runner for his use of carbon-fibre prosthetics.
