Less than two weeks after his sentence for the killing of girlfriend Reeva Steenkamp was more than doubled, disgraced South African athlete Oscar Pistorius has been injured in a prison brawl.

The disgraced Paralympian was allegedly involved in a fight over the use of a public phone according to reports.

The South African prison department has launched an investigation, in terms of standard procedure, to “establish the facts and to ensure that appropriate action is taken as incidents of assaults are not allowed”.

The brawl took place on the 6th of December, 10 days after south African prosecutors successfully argued that the six time Paralympic gold medallist  “shockingly light” six-year sentence should be increased.
