Carl, Oscar Pistorius' brother, seen here arriving at their uncle's South African home Sunday, where the athlete is staying while on bail on murder charges.

According to his lawyer, Carl is also facing charges -- of culpable homicide -- for allegedly killing a motorcyclist three years ago in a driving incident, but refused to comment further.

Oscar Pistorius, suspected of murdering his model girlfriend on February 14, has been ordered to avoid all witnesses and his Pretoria home.

He is also to abstain from alcohol and report to police twice a week after giving up his passports and two firearms.

The next hearing is set for June 4, when the court is expected to set the date for his murder trial.

Pistorius could return to training in a week's time, even though his competitions have been cancelled.
