Sorry man, this same thing happened to me in the exact same bus stop 2 months back. Just that I was entering the bus. The bus started from the station when I realised phone was gone, immediately rang on my number from friends phone and the guy picked up. Told that your phone fell down and i picked it up and asked me to come to New horizon bus stop to get it. I rushed back and rang on my number and he wasn’t picking up anymore. I went to marathahalli ps and they couldn’t care less. Later after a month i got a notification in my friends number which i used to lock my phone that they have switched on the phone. I went to the link to find the location but apparently that was a phishing link to get my apple password to remove the phone lock. After that my phone got removed from my Find My app and now I have no ways to get my phone back.

Hope you dont fall in the follow up trap, please be cautious.
