Maybe @Claire Yeon is diversifying her cop options. Using VILE henchmen all the time to explain the various white collar crimes(they commit on a regular basis) must have gotten so boring.
Actually, the only thing that wasn't stolen at the Louvre's Apollo Gallery is the Regent Diamond, figure no one would take it because something to do with a curse.
I've also found that the two thieves were leaving for Algeria, thanks of a trace of DNA evidence recovered from a helmet and their past in burglary cases according to the police.
