4 drivers came to attack me today morning. 3 tamilnadu pravasi employees who trying to board in a pvt auto-rickshaw, the prepaid drivers ordered them to use prepaid taxi and scolded them. I questioned this.pvt vehicles are not allowed here? Any authority existing to control these criminals? A name board should be displayed on every drivers operating taxis in this airport.
