Help!!! phone stolen inside Chattarpur Metro rail

Hello everyone, my phone was stolen from Chattarpur metro rail yesterday at 1425 hrs.
There were 4 people surrounding me and unnecessarily creating crowd one of them was quite fat. Within a seconds it was stolen from the front pocket of my trouser.
I did all the necessary procedures, filed stolen report, checked cctv but cctv image was so grainy couldn’t see clearly. Further only cctv footage of platform was available and no footage from inside the metro was accessible.
The police constable at the metro stated that since morning before me already three phones were stolen and a gang is operating and he knows them.
No update from police till the time of posting.
Imei last location is from the metro after the crime, it was switched off and no activity since.
I got replacement sim. Logged out of all accounts and through find hub initiated factory reset.
Advice needed:
Phone model: Motorola G85
What more i can do?
