NEW DELHI: Among the several places where protesters assembled on Saturday, besides the Delhi Police headquarters, were the Gandhi Nagar police station, AIIMS, India Gate and residences of union home minister Sushilkumar Shinde, Congress chief Sonia Gandhi and chief minister Sheila Dikshit. New Delhi was turned into a fortress with water cannons stationed outside the residence of the home minister but the cops denied allegations of imposing section 144 in the area.
