Police spotted the vehicle and a high-speed chase ensued. The wanted men are alleged to have opened fire on police, who retaliated. The driver lost control of the vehicle just before the N2 off-ramp and the vehicle overturned.
Members of the police and metro police cordoned off a portion of the M7 highway and the three alleged robbers were treated by paramedics before being arrested at the scene.
Police did not immediately respond to queries.
