Pretoria - A business owner and his colleague are in a critical condition following a shooting in Pretoria on Friday.
The shooting is believed to be a hit, but a motive is not yet known.
The shooting occurred just before 16:00.
Police said Wandile Bozwana, who owns energy drinking company Orgazma Special Energy Drink, was travelling on the N1 north from Johannesburg with colleague Mpho Baloyi in the driver's seat.
A silver grey BMW M3 allegedly pulled next to their car near the Garsfontein off-ramp.
According to police, the suspects in the car started shooting at the branded yellow Renault Clio.
About 12 bullets hit the car with nine of them hitting Bozwana, five in the lower back.
Baloyi was shot twice, but managed to drive to a car dealership near Menlyn Shopping Centre to seek help.
Police spokesperson sergeant Asnath Malatji said the pair was coming from Sandton heading to Mooikloof.
She said they were investigating an attempted murder case.
"At this stage, we don't know the motive, but are appealing to people who might have seen the incident to come forward with information to ensure the suspects are arrested," she added.
The bullet-riddled car was still being combed for evidence more than an hour after the incident. The pair was taken to Unitas hospital.
The scene attracted several bystanders.
Motorists on the N1 at the time of the incident called EWN radio station and said they had seen one person jumping out of the car and opening fire at the other vehicle. The BMW then sped off. No arrests have been made.
