Oscar Pistorius' spokeswoman said he has reported to authorities in Pretoria as part of his bail conditions.
Lunice Johnston told the Associated Press that Pistorius has visited correctional officers, but did not reveal where the meeting took place.
Pistorius, who was released on bail Friday, is accused of premeditated murder following the death of his girlfriend, Reeva Steenkamp, in the early hours of February 14.
Prosecutors claim the couple argued before Steenkamp was killed. Pistorius says he mistook Steenkamp for an intruder and that the shooting was an accident.
