Tussle within the Chhattisgarh Congress has spilled onto the street following a road rage incident involving a tribal MLA and a relative of state Health Minister TS Singh Deo. On Saturday evening, the convoy of Congress MLA from Balrampur, Brihaspati Singh, was passing through Ambikapur. Apparently angry at the vehicles overtaking him, a young man intercepted an escort vehicle, smashed its windshield and verbally abused the security personnel.
