A Cape Town businessman and his associates were robbed at gunpoint during a business meeting at a northern Johannesburg restaurant, said one of the victims, who declined to be named.

The six men were seated at an outside table at the Istanbul Kebab, a Turkish restaurant in the Sunninghill shopping centre, on Wednesday when the incident occurred.

A video clip of the robbery, which has gone viral on social media, shows a male in dark clothing jumping over a wall and pointing a firearm at the men. Another suspect wearing light-coloured clothes joins him, waving his own firearm at the group.

The victims are forced to the ground before the robbers remove watches, wallets and other items from each of them.

The men are then seen fleeing on foot.

During the incident the Cape Town businessman, whose identity is being withheld for his safety, was struck by a bullet but not seriously wounded. He returned to Cape Town on Thursday.

The man declined to be interviewed by the African News Agency about the incident.

Online publication SApeople quoted the restaurant owner as saying his son was at the establishment at the time of the robbery but was unharmed.
