Patel Travel — shawl got stolen

Trip was from ahmedabad to reliance on 19th may night 11:35 pm bus of patel tours and travels. Bus number busno: gj01et8294
Serviceno: dwr-brd. Mine was seat f. The rest stop arrived at around 2 am and like everyone gets down keeping their blanket/shawl on their seats i went down and hardly within 3-4 minutes i was back when i saw my shawl was not there
Someone stoled it and in the night i didn't find it right to create a scene and disturb everyone but then this is a matter of concern safety and security point of view. Cctv or something should be done to avoid such things. If some valuable are stolen who will be repsonsible because practically it is not possible to pack the stuff and take with you during any stop and normally no one does that because cheap passengers don't come in bus
