what do you do if you find a kitten outside at 3 am with a collar?

I was able to build some trust and now it's extremely friendly, I live in an apartment complex with no pet doors in central NC, should I bring it inside and see if it's chipped in the morning? I don't wanna leave it outside if it might have no home, but I don't wanna steal someone's cat

It looks like an adolescent or a late kitten? The collar has nothing on it, it's just a piece of white flexible plastic with a buckle...

Removed the "HELP" since people in the other thread were able to help me figure out that I should leave it be outside
