P0lice Stati0n, roughly 5nine R0seberry Ave. Prest0n. Not really much to see, just a bunch of rooms. Probably the only interesting bit was the cells (could only gain access to one wing) with the scratched messages on the walls from the inmates. The new police station is less than 50m up the road and the old one just sits there now.
For those adventurous enough, there is another abando p0lice station on the corner of S3rvic3 St. and Be11 St. C0burg. But I haven't had any luck getting into that one.
