Thanks for enjoying the game, glad you liked it! As for after getting arrested, you can either walk up to the cracks in the wall to move into the right cell and open the cell door, or open the one in your cell (not recommend since it's a very hard fight). There is no key as it's implied that the bots did such a shoddy job that they left the cop rat with the keys, so they are defacto open. Hope this helps!
