Cutting Banana Tree without any reasons

Sir, I am venkatesh, working in IT company in Chennai. On 30th July, around 10 AM, My neigbour's construction work Kumar told me that one of my Apartment Owner Mr Senthil Kumar (Work in IT Company) without my persmission, he cut down the well grown tree at 4 AM (early morning) on 30th July, that was witnessed my Kumar. So, initially I asked Senthil Kumar, be refused that he never done. But 11 am I have given written complaint to Police Station in Velachery, Chennai. After several repeated calls by Police, Senthil Kumar came to station and finally agreed he cut down for no reasons. Important point to note here, his car is in my parking lot (i rented free for his new car needs more space and his parking area is used by myself for my bike only, as his parking lot is closely to construction debris falling area. Even, I sacrificed for him, as my daily using bike is rusted with cements and debris. Also, only banana and drum stick tree are in 2X2 space - rain harventing area (appxly) that did not distrub any one in common area and sapling growing since last 3 years. All the sudden without any reason behind, or any triggering personal enmity, he did above killing to my kid like trees. He also, used banana tree leaves for last 1 year. Just for your information, I am green initiative for last 10 years, trying to do community initiative of planting around chennai. My question; apart police warning to him and written statement collected from senthil (opponent party), Apartment decided to cut down all banana tree that is grown in rain harvesting area. But I need compensation, i spent more than 5K and going through tragic shock. Note : Also, I am panic about his odd behaviour of cutting tree at 4 am without any prior notice or request to do or even not put his act to early held Apartment meeting. I came to know that from source, he has some mentor disorder in his family history. This is big concern for my family safety, as I am leaving long term assignment to scotland from my company work. Kindly let me know on how to get compensation for my loss and tragic shock due to opponent odd behaviours repeated in different form often.
