JOHANNESBURG -- Oscar Pistorius was treated for minor wrist injuries at a hospital and has been returned to a South African jail where the Olympian is serving a six-year sentence for killing girlfriend Reeva Steenkamp, prison officials said Sunday.The report of injuries to Pistorius, who denied he had attempted suicide, came as athletes began competition at the Olympic Games in Rio de Janeiro. Pistorius and his coach said before Steenkamps 2013 killing that they wanted to retire together at the Rio games.Pistorius told officials that he suffered the injuries after falling out of bed, said Singabakho Nxumalo, a spokesman for South Africas correctional services department.The former track star was initially treated by medical staff at the Kgosi Mampuru II prison in Pretoria, and then transferred to Kalafong hospital, said Manelisi Wolela, another official at the department. Pistorius was returned to his cell on Saturday, and an investigation is underway.Oscar Pistorius denied speculations of a suicide attempt, Wolela said in a text message to media.As a policy principle, we cannot further discuss a particular offenders personal condition in the public domain, he said.Pistorius family declined to comment, referring inquiries to the correctional services department.Pistorius has been held in a single cell in the hospital wing of the prison, reducing his interaction with other inmates.During Pistorius sentencing hearing in June, a psychologist testified for the defense that the athlete was a broken man whose mental state had deteriorated over the last two years, and that he should be hospitalized and not jailed. Prosecutors have challenged such assessments, saying Pistorius has an aggressive streak and may have played up vulnerabilities in an attempt to win leniency from the judge presiding over his case.Commenting on the decision to send Pistorius to a hospital, Nxumalo referred to past reports of tension between the convicted murderer and a prison nurse who testified about alleged confrontations over medication and other issues while the runner was serving an earlier manslaughter sentence. Pistorius defense team suggested those reports were exaggerated.Last month, South African prosecutors said they would appeal Pistorius jail sentence, saying it was too lenient. The double-amputee athlete, who was sentenced on July 6, could be released on parole after three years. The prescribed minimum sentence for murder in South Africa is 15 years, though a judge can reduce that penalty in some circumstances.Pistorius also previously served one year in prison for manslaughter for shooting Steenkamp, a 29-year-old model and reality TV star. That manslaughter conviction was upgraded to the more serious offense of murder after a prosecution appeal, leading to a new sentencing.Pistorius shot Steenkamp multiple times through a toilet cubicle door in his home in the predawn hours of Valentines Day, 2013. Pistorius testified that he killed Steenkamp by mistake, thinking there was an intruder hiding in the bathroom. Prosecutors said he shot her intentionally after an argument.Pistorius, known as Blade Runner for his carbon-fiber running blades, gained worldwide fame when he ran against able-bodied athletes at the 2012 London Olympics, the first amputee runner to compete at the Games.Pistorius was born without fibulas, the slender bones that run from below the knee to the ankle. His lower legs were amputated when he was 11 months old.Air Max Plus Near Me . -- In one brief spurt, Brazil turned a close game into a rout and proved again it will be a strong World Cup favourite.
