ANC treasurer-general Mathews Phosa' a driver will testify as a witness in a hijacking case next month.
The driver, identified only as Lerato, was transporting Phosa's mother to Sosha-nguve north of Pretoria earlier this year when they were hijacked by two men at gunpoint.
Phosa's mother, Reshoketsoe Phosa, and her younger sister, Mokgadi Phosa, were passengers in the car during the incident.
The car had stopped at a stop sign when two men approached the occupants and ordered them to get out.
The gunmen told the three to lie down before driving off in the BMW X5.
The car was fitted with a tracking device and was traced within minutes by a tracking company.
The police in Pretoria North immediately had the vehicle in their sights.
Realising that they had been cornered the suspects tried to force the police off the road before speeding down a busy road.
The police followed the vehicle until its driver lost control and crashed into a building.
A shootout ensued between the police and suspects. One suspect was shot in the buttocks.
His accomplice managed to escape and is still at large.
The injured suspect allegedly refused to reveal the identity of his accomplice to the police.
The suspect is expected to appear in the Pretoria North magistrate's court on September 11 to face charges of hijacking .
