Is anyone able to read Japanese? [résolu]

I came across this bronze medal and have no clue what it says. 

Any help would be greatly appreciated.

Thank you

The top two lines translates as "Kanagawa Prefectural Police Headquarters." Don't know about the last line.

Thank you

That definitely helps

Here's a picture of that building:

Maybe the last line says "February 1992"

I agree the last line is a date.

Could the third character be a variant of the old Kanji for 30 (丗)?

If yes, it is 2018.
