9:00 AM PT -- Raheem "Fuzz" Thomas is scheduled to make his initial court appearance Wednesday afternoon in Paterson ... and law enforcement sources tell us cops are preparing for the worst. We're told there will be extra patrols outside the courthouse due to worries about rival gang members.
The same guy busted in the Fetty Wap shootout is now charged with jacking his chains -- Raheem Thomas was arrested again Tuesday night.
Cops booked Raheem, aka Fuzz from Muscle Team Entertainment, for armed robbery and gun possession. Our law enforcement sources tell us cops booked him based on seeing video of the robbery where Fetty's jewelry -- including his 1738 chain -- was stolen.
