JOHANNESBURG - South African Paralympic gold medallist Oscar Pistorius, who was sentenced last month to a six-year jail term for killing his girlfriend, was treated in hospital for injuries to his wrists on Saturday and was returned to prison, an official said on Sunday.

"Oscar Pistorius denied speculations of a suicide attempt. As a policy principle we cannot further discuss a particular offender's personal condition in the public domain," said Manelisi Wolela, a spokesman at the Department of Correctional Services.
