I have bought a flat in resale in kharghar , navi mumbai. registration is done , all payment have done. But the man is absconding & not done the sale deed & given the power of attorney to his wife & daughter. The civil case is going on, but i want to file FIR for cheating against all of them, the man his wife & daughter. But police are denying saying that it is a civil matter & since the civil case is going on police cant investigate. Is it so? please advice.
