Can anyone tell how to deisprove an fasle allegation bythe police by sieze a fasle deadly weapon(local sword)

but the complainant does have a small abrasion(Scratch) actually accused didnot hurt him but the complainant only hi him and filed a counter case. police bribed what to do help me out with any citiations to say that the elation of finger print of weapon and the accused or the injury and the weapon used.

Seek the expert opinion as to whether such injury can be caused by such a heinous weapon - The reason such weapon has been planted is to bring the offence within the somewhat serious S.324 IPC
