Gauteng police are questioning a man, after a four-year-old boy was killed in a hijacking in Reiger Park, east of Johannesburg over the weekend.
Spokesperson, Colonel Noxolo Kweza says the man is not a suspect.
She says no arrests have been made and police are still searching for the suspects.
Kweza said the police hoped the man would be able to give them information which could help in their investigation.
She denied a report that a man linked to the hijacking had handed himself over.
The boy, Taegrin Morris, died after being dragged behind a hijacked car in Boksburg.
The suspects allegedly sped off while his mother was trying to unfasten his seat belt.
She pleaded with the hijackers to stop, so she could save the boy, but they apparently refused.
Taegrin was dragged next to the vehicle.
The abandoned car was later discovered several kilometres away in Boksburg, with the dead boy still tied to the seatbelt.
