Law enforcement sources tell us Lopez -- who we're told works as a bouncer at a bar in Calabasas, CA -- was also booked for felony burglary and his bail was set at $50,000.
As we first reported, the other four suspects -- Rachel Lee, Diana Tamayo, Courtney Ames and Alexis Neiers -- were also arrested yesterday.
Nick Prugo -- who was arrested back in September -- has already been charged with two counts of felony burglary.
