Anticipatory bail in case of complaint by neighbours for huge assets

Dear Sir I am a central government employee. We have a very problematic neighbor who keeps fighting with all the neighbors. This neighbor has complained to CBI that I have disproportionate assets. Based on her complaint and pressure from her, they have taken up the case and filed an FIR on me during october 2016. After filing FIR, they have searched our house where nothing was found. After search is completed, they have asked for some documents asking for sources of income, expenditure etc. All the details are submitted during Jan 2017. The investigation is in completion stage. At this stage, I have decided to resign from my job. My resignation has also been accepted by our authority. After resignation, I will no longer be a government employee, but a private person. Is it required at this stage to take anticipatory bail..? As on date the case is still in investigation phase. I am almost certain the case to be closed as there are no disproportionate assets as complained.
