83 crpc not executed by IO and IO says that he will file closure repor

My mother has filed a case in 406/420 ipc and 3/4 Dowry act. Anticipatory bail of accused has been rejected by patna high court and IO requested for 83 crpc and same has been issued on 22/5/19 but I.O. in connivance with accused persons is not complying the 83 crpc order. I have doubt that IO might submit closure report in my case. What precautions i must take? Can 83 crpc order be returned to trial court unexecuted? After court take cognizance what will happen to the earlier order under 83 crpc? If IO and his supervising authority has malafidely filed closure report in my case what steps i need to take??
