Inform you that our neighbor's they maked Un-Authorized construction. (E.g.:Flats No.: 13-B, 13-C, 14-B, 14-C, in Pocket D-2 Flats). They extend there flats illigaly & not follow DDA Conditions and Delhi Government rules. When we take any action for that, The flats owners abuse us & threatened us or provoke us to fight. The all flats owners comes same time to fight with us when we are not in home. This is unsecured for us and my Family. They also damage our plants and tree which is inappropriate and against the law. They coverd Road(path) space which is between flat and park. They don't allow anyone to access the road.
