For the same act, it is not possible to register two FIRs or conduct two trials. You can use Section 300(1) of Cr.P.C. in your support, which lays down as under:
“300. Person once convicted or acquitted not to be tried for same offence.—(1) A person who has once been tried by a Court of competent jurisdiction for an offence and convicted or acquitted of such offence shall, while such conviction or acquittal remains in force, not be liable to be tried again for the same offence, nor on the same facts for any other offence for which a different charge from the one made against him might have been made under sub-section (1) of Section 221, or for which he might have been convicted under sub-section (2) thereof.”
