Surveillance

While Petrenko is charging the battery you brought him to repair the BTR, he has a task for you.
A small rat has been spotted stealing food and various stuff all over the bar lately. It's clearly domesticated and trained by somebody to steal. Petrenko wants you to track the perpetrator to its lair, as the rat stole his antique wrist compass. You should come to him after mignight to start the tracking.
== Walkthrough ==
Come to Petrenko's room from 12:00AM to 3:00AM, into the place marked on your map. After a couple seconds, a white mouse will appear in the corridor outside the room. You should follow it at certain distance to not fail the task - not too closely, but not too far away either.
After traveling across the Bar area in a winding path, the white mouse will come to two red containers and disappear. Six aggressive mice will spawn and attack you. This is the lair; look behind the containers for a small box with Petrenko's wrist compass in it.
Upon finding the wrist compass, bring it back to Petrenko. He will reward you and give you the charged battery for the BTR.
== Notes ==
* The mouse will stop on its path in scripted intervals. If you are too close (5m) or too far (20m) at the moment of it stopping the quest will fail.
* The mouse shows up as friendly in BPOs binoculars unlike other mutants.
