The police are yet to make an arrest after a car carrying members of the VIP protection unit allegedly hit and killed a pedestrian in Ulundi over the weekend, KwaZulu-Natal police said.

Director Phindile Radebe said a case of culpable homicide was under investigation but no arrests had been made.

"The investigation is underway... but it takes time," she said.

Maqhina Sibiya was hit and killed, allegedly by a VIP protection unit vehicle in which African National Congress president Jacob Zuma's bodyguards were travelling on Sunday morning.

Zuma was not part of the convoy, heading to an ANC rally in Nongoma.

The Independent Complaints Directorate said it would add the incident to ongoing probes into the unit's conduct over the past 12 months.

Among the cases being investigated was the assault of a motorist on 3 January, allegedly by President Kgalema Motlanthe's VIP officers, on the N12 near Johannesburg.

The motorist's car allegedly "got too close" to Motlanthe's convoy. VIP unit members fired shots at the vehicle and then confiscated equipment belonging to SABC journalists when they arrived on the scene.

A report on these incidents was due to be released late last month. ICD spokesperson Tommy Tshabalala said on Sunday that they were struggling to get statements from some of the victims.
