"Some people have put out posters and hoardings congratulating about the victory all across the city. This is not right. We are precisely against this kind of politics.
"If the volunteers want to celebrate victory, they should serve the people," Kejriwal posted on Facebook.
Kejriwal also asked people to report to authorities if they came across any such poster or hoarding.
Within an hour of posting the message, it was liked by over 14,000 people and shared by over 1,000.
