We want to speak to him now‚" said one of the men as he spoke on the microphone stand.They were sitting down at the reception area of the Diagonal Street building where Vadi earlier addressed reporters announcing that Uber driver partners would get legally licensed by the department.The angry men assaulted Vadi inside the building just as he concluded the tour of the operating licences registration unit. As Vadi stretched his hand to one of the men‚ the assault began.He fell on the ground and more men joined the attack.Security personnel in the building were just thrown to the sidelines as the angry men went on a rampage. "What are you doing here?"‚ the men asked as they attacked the MEC.He rose to his feet as he tried to reason with the men‚ but they charged towards him again‚ forcing him to flee for his life.He ran as the men continued to chase him. He find a place he could get into and it was immediately locked. Security guards seemed overwhelmed by the sudden attack.Police then arrived in the building - the Tactical Unit‚ Johannesburg metro police and other officers were guarding the area.The men are believed to be drivers of metered taxis who are unhappy with the Uber taxis‚ which they say are taking their business.TMG Digital/The Times..
