Oscar Pistorius, who turned 37 this week, earned his nickname as the "Blade Runner" because of the futuristic carbon-fibre prosthetics he used for competitions.
A woman identified as Martha Okpanachi, has been accused of cutting her 20-year-old stepdaughter in the face and thigh with a razor blade in Mararaba town, Nasarawa state.
He added: "He reached into his right pocket and pulled out what appeared to be a knife or a razor blade, maybe a box cutter and lunged at the Congressman."
