A little bit exaggerated...
Two security (APS) guys came on board, no guns were drawn however the APS guys certainly are armed. 5 passengers (combination of males and females) were escorted off.
There was an "altercation" (fisty-cuffs) between these pax, and the crew (as I would) decided to send-em-back.
The whole incident was handled very professionally in my opinion.
(I know as I was a passenger on the flight)
