Look at it this way: do you want police not disclosing who they arrest?
Name, age, city is pretty common; especially name and age of someone arrested. I'd imagine it public records.
Some quick googling for recent examples. I just looked for news articles, not sure what if the police release has more residency info on the ones that aren't listed in the articles.
I've seen an article about this suspect that includes their address, what they paid for the house, other places they've lived, etc. Different to police releasing information though.
Yea, a great deal of information is available to the public once you have their name and city. Which isn’t really a new thing, many phone books used to include peoples address alongside their names and phone numbers.
The linked article contains the full name, age, and city of residency.
