Agriculture water well dispute, police force me not to use

Hi There, My name is Anil, I bought agriculture land in 1999 and dug water well in 2012, lucky I got water also, now my neighbour farmer name Rashid also tried digging water well close to my water well thinking he'll also get water but unfortunately he didn't not, now Rashid started saying previous owner of my and his land was same, so I also have share in Anil,s water well (its me), and started threatening, I filled complain against him in Police, unfortunately police was known to him , when we both went to police station , Mr Vyas senior SI threatened me and gave me 3 choice, 1, give share to Rashid , 2nd. Both do not use water and go to court for fight, 3rd I'll put you in jail and since I am working in private job, if I go jail I'll loose my job, then police forced me , my father and my brother to write on plain paper that we both parties will not use well and go to court for decision, now My own water well but I can not use and when I went to court it's being 2 year judge keep changing but no decision, My question, can I fill case against police in court saying they threatened me and made me to write on paper and now they are not allowing to use well water ?
