Safety tips for recovering your own bicycle

My ebike was stolen around early May 2023. I posted the stolen bike on Bike Index.
Now - in August, I received a TEXT message from someone saying they think they “bought” my bike and saw it listed as stolen on Bike Index and am I offering a reward for it?

They said they had cops “run the serial and it came back clean” and do I want to meet up to see the bike?
It all sounds weird. My ebike was stolen WITHOUT its battery and charger, I still have that. I suspect this is the thief and being unsuccessful in selling this ebike with no battery, he/she is trying to get some $$ from it by getting ME to pay a reward.
I’ve called local police (I filed a report back in May) but slow to get the wheels turning. Posting here in case anyone has suggestions on how to proceed.
Thanks a bunch!
