My fathers will favoring me & claiming rent from it

Sir, i am 40 years old pvt school teacher. I have one elder brother running hotel. My father had 2 self earned properties. I am polio affected & physically disabled. So my father wrote a will on aug 2013, favoring me.
In that will, he said that a small building of 1155sq ft (1 house & 4 shops), which was his self earned property belongs to me, and i have all the rights to sell or do anything after his death and the will was registered in sub registered office.

In that building my elder brother residing in a house, & running a hotel in 2 shops. Remaining 2 shops were rented & rent was collected by my father.

3 months back my father passed away.

Now as a courtesy of love, i asked my brother to stay in that house, and he can continue his hotel in that shops. Also am not asking any rent from him.

But when i tried to collect rent from the rented shops, he (my elder brother) collects those rent and refusing to give it to me.

What can i do sir. I am having the properties original document, Original registered will. If u file a petition in police station, will it become a civil case and lasts for many years. Please guide me sir.
