Air India — Stolen jewelry from carry on hand bag at security checkpoint

I travelled from Delhi to Toronto on 29th January and had some jewellery in my carry bag. I realized my carry bag went for re screening while I was waiting for it to come to me. There were few mins before the carry bag was screened again and it was on the belt in hands of the officer which was suspicious and unrequired. There was no other time that my bag was touched by anybody else in the trip and after coming home I got to know my bag didn’t have one pair of earrings, a bangle, and 2 rings - all gifts of my family while I was departing.
