The angry protesters also torched six municipal vehicles and damaged four others, including a TMPD bus."He condemned the actions of the protesters and questioned why people would destroy structures which served them."The protesters' action would inevitably lead to the disruption of basic services. The city is baffled as to why protesters would vent their anger at the instruments of service delivery, instead of protesting peacefully," he said."We call upon the residents to use existing channels to air their grievances and not resort to acts of criminality and destruction of property."
