Neighbor places asbestos sheet as boundry

We have 3.5cent land which includes a house in it. We don't have much space left between the kitchen exit door and the boundary wall (1mtr). We have a boundary wall built , which is of 3ft height. However, our neighbour place vertical asbestos sheets as a barrier on his side. This restricts light and the back side is pretty dark. Moreover, there are chameleon, rats and frogs and sometimes snakes go inside the space between the ripples of this asbestos sheet. These creatures sometimes see exiting, or passing through or sit right out of the kitchen door. We went to a police station to complaint about this asbestos sheets and the threats it poses. The police says we are not supposed to kill snake even if you see one. I am worried what if the snake bites us and we kill it as precaution. We will be held responsible. All we ask was to remove the asbestos sheet and if he wants he can build a taller boundary wall on his property. But the police is saying us to increase the height our boundary wall. We agreed we can make a wall upto 5ft. But our neighbour is demanding a 7ft wall to be built by us on the existing wall. Otherwise he wont remove the sheets.. Police sounded very biased and was letting my mom talk because the first few minutes our neighbour was doing a character assisnation to portray my mother is a bad lady. Is there any legal possibility we can get this addressed?
