Air India — stolen from checked in baggage

I had travelled from DXB to CCJ on 02/08/2019 in airindia (ticket copy attached for details). After collecting the checked in baggage from Calicut airport, I went out of the airport and hired a taxi. I opened my checked in baggage to takeout Indian money which I kept in a wallet in a bag inside the checked in bag. But, I found that my wallet was kept outside the bag with no money (3000 INR stolen). Fortunately they didn't steel my ATM card, that's why I could mange to reach home.
I know I shouldn't have kept my wallet and money inside the checked in bag, but last minute hurry from DXB airport, I forgot to take out from checked in baggage.
I am not expecting you to return my money, but at least I want an investigation to find out the culprit (you can check CCTV footage). I know it is a habit for the some staffs in Calicut airport to steel from baggage(we have seen and heard many such incidents). If you make an investigation, they will be little afraid to open the baggage of passengers.
Hope you will understand and do an investigation . Expecting your feedback.
Thank you.
