“AirTag Found Moving With You” AirTag Detected

I recently moved apartments and on day 3/4, I get a notification that says an “AirTag found moving with you” and “your current location can be seen by the owner of this AirTag”.

I don’t own any AirTags, only AirPods. Also what is freaky - on the map for the notification is a red line that shows up between the new apartment and the old apartment. And I did visit the old apartment but it was a quick stop.

In my Find My app, it shows as 3 AirTags notifications under “items detected with you”. On the day of the initial notification, I was able to play the sound but could not find it. I am unable to play the sound since that night as the “AirTag is not reachable”. As of today, the notifications have completely disappeared.

Could someone please shed some light on this? Could this be a neighbor or a stalker or a software issue? I have read some people have also had the same issue. Please help!! Thanks!
