'The decision was taken because it is monsoon season, the posters or hand bills or pamphlets stuck on the walls of the public properties get soggy and can be easily removed,' Mehra explained.

Teams from MCD's Town Hall headquarters and 12 zonal offices would be deployed to remove material off walls starting Sunday.

Under the Delhi Prevention of Defacement of Property Act 2007, defacement of public property or walls is a cognizable offence and doing so can warrant imprisonment for a term up to one year or fine of Rs.50,000.
