Andhra Pradesh State Road Transport Corporation [Apsrtc] — lost backpack bag with wallet having gold ring, a silver ring, mobile orginal documents and other things

On 11th dec 2019. While travelling from kanigiri in prakasm dt to chennai in apsrtc bus.. We lost a bag placed on the lugagge rack above us. It has a wallet with original pan card, house keys, one gold ring with a stone in the middle, one silver ring with a stone in the middle, one oppo a3s mobile, power bank, mobile charger, cash around rs 3000 amd some clothes. As soon as we found the bag was missing we have been trying to call the lost mobile. But it is switched off. It is fully charged upto 90 percent when kept in the bag. So we are sure that someone switched it off. And it never got switched on from last 3 days. We approached kanigiri police station through our relatives to file fir but they are not ready to file saying that the theft did not happen in their jurisdiction. Whom should we contact now. Please help us
