AIIMS — lost my bag

I was travelling in an auto rickshaw yesterday from "sarojini nagar" to "aims metro station" in delhi.
I lost my purple color handbag in that auto. My handbag has all my bank documents and especially some very important papers related to my education. It has my address proof and contact details written all over it.
I personally went there and inquired all the auto stands around that area, to find that particular auto. But hard luck.
Can anyone suggest me some good way to trace it back?? If anyone found it, please return it. My name is sangita rana. Please please that is very important for me.
