Western Cape police officers are in hot water again for allegedly shooting at another group of workers travelling in a taxi. On Tuesday, 11 staff from Ciba Packaging were on their way to work on the N1 when police allegedly shot at them. No one was hurt.Last month officers opened fire on a taxi carrying Nando's staff, killing one and wounding another.Earlier this month McDonald's staff in a taxi were shot at. Two were killed and five wounded.In all three cases the taxis were mistaken for vehicles involved in crimes.Independent Police Investigative Directorate spokesman Robbie Raburabu said the latest incident would be investigated. Police had been looking for a taxi with tinted windows and the shuttle police shot at apparently fitted the description.Raburabu said: "When they tried to stop the vehicle, it didn't. But then they fired warning shots and that is when the vehicle stopped."Ciba Packaging employee Julia van der Vent was travelling with colleagues from Paarl to Montague Gardens when police gave chase.She said: "A man in a white car was next to us, he was leaning over the roof pointing a gun at us. Then we heard two shots."When the taxi stopped in the vicinity of Goodwood they were ordered out."There were policemen everywhere. I saw what looked like snipers on the bridge, armed police lying between shrubs and standing on the island."Police spokesman Constable Noloyiso Rwexana said: "Cases of reckless and negligent driving, and failure to obey an instruction of a police official, are being investigated against the driver of the Quantum. A case of pointing a firearm has been registered against SAPS officials."Asked if the three incidents could be linked, or if criminals were cloning numberplates of taxis to use on their vehicles, she responded that "all possibilities are being investigated".Raburabu said the police did not identify themselves, adding: "As a normal citizen, why would you stop when you are being chased by a vehicle like this?"Senior researcher at the Institute of Security Studies Johan Burger said police could only use deadly force if there was a real threat.But, he added: "In the subconscious of police members there is the fear that they could be next. They are the guys in the front line. These robbers are armed in most cases."..
