Neighbour is opening window on my side without leaving a margin

Dear sir, My neighbour is building his house just near my boundary wall leaving no margin on his side. On ground floor, he did not open any window on our side. But on first floor and second floor, he opened a window on our side leaving no margin. We asked him to close the window as he has left no margin, but he refused to do so. we tell the problem to several peoples and when they talk to him, he said that no one can do anything against me, i will do what i want, he is very known journalist of our city and his wife works in police commissioner office. and we are just belong to middle class family. his constructional material is also fall on the land which is open in our house due to that the open land is full of cement and concrete, and he is putting बल्लियां in our open ground since last months, he started plaster in our side than stopped when we requested him to close window, and start working inside the house. also he is building 3-4 floor building on 20 feet road. does there is any law regarding to building height to road size. What legal actions can we take against him? Is it possible to close the window by law?
