private complaint case acquittal and deletion of record

Dear members, We filed a FIR on our relative in 2008 and police charge sheeted him. He entered in our house drunk. In 2009 after 9 months , our relative registered a private complaint against us. His complaint was that police took our favour in 2008 and registered case against him. He also gave application against us in 2008, but police did investigation and found nothing against us and found our side of story true and hence a case registered against him. In 2015 court acquitted us in this private complaint. Basically, I don't have any criminal record with police as no FIR registered against, no arrest and charge sheet. Police was in favour for the whole case. Is there any way I can delete our acquittal record from court? I am planning to go abroad. I recently got passport renewed with clean police verification and police has no record against me. I just want to delete even this acquittal from court for peace of mind. Please guide me through if there is any way to delete it. Any help will be appreciated. Regards
