South African Olympic and Paralympic star Oscar Pistorius has denied a charge that he murdered his girlfriend, Reeva Steenkamp.
Ms Steenkamp, 29, was shot dead at Mr Pistorius's home near Pretoria on Thursday.
Dubbed "blade runner", he made history last summer by becoming the first double-amputee track athlete to run in an Olympic Games.
"The alleged murder is disputed in the strongest terms", said a statement released by Mr Pistorius's family and management company after the court hearing.
Police were called to his home in the early hours of Thursday morning.
They found paramedics treating a 29-year-old woman with four gunshot wounds to the head and upper body. She died at the scene, and officers recovered a 9mm pistol.
A post-mortem examination was being carried out on Friday but the results will not be made public, police said.
