Chief Minister Arvind Kejriwal along with his ministerial colleague Manish Sisodia, was forced to take refuge in his small blue car as the skies opened up Tuesday morning.
Kejriwal is now listing grievances of common man, sitting inside the car. Some Aam Aadmi Party (AAP) workers were seen covering themselves with huge vinyl party posters to protect themselves from the rain.
Although there was a small crowd in the morning, AAP supporters started thronging the protest venue gradually and raised slogans against Delhi Police and Home Minister Sushilkumar Shinde.
