Can residential property be used as a playground in Bangalore?

Earlier I had posted about an apartment converting a 30\*40 site into a playground. Now I will tell you what happened once I complained about the noise, the apartment junkies started creating more nuisance by purposely banging on the grills (when we were on calls) especially the women, children were told to make more noise, tried to intimidate us by ganging up next to our property, used loud speakers, laughing at our plight. Some of the children would actually come into the property to take the ball and some of them even broke our drainage pipes, water pipes connected to the water tank and the list just continues. Now I want to ask all those people who think its okay to have a playground right next to a house, how do you justify this? Please think...
