BUG
This has happened multiple times. As an addition in the 0.4.7 update for LSPDFR, suspects that have escaped from cops can reappear.
However, this new function is quite buggy. When I take an previously fleed suspect into custody and deliver them to the police station, they may still reappear later in the same vehicle. This can be quite annoying as when the fleed suspect is spawned again and drives near the player, it takes off and can crash into crime scenes, the vehicle, etc.
I hope this can be fixed and good luck during these times.
