Former UFC star Dustin “The Diamond” Poirier was arrested at Hartsfield-Jackson Atlanta International Airport following a chaotic confrontation.  According to TMZ and police reports, airline staff denied Poirier boarding on a Delta flight due to intoxication. Wild bodycam footage captured the 37-year-old fighter screaming profanities, squaring up to an airport employee, and aggressively daring officers to arrest him, shouting, “I’ll fight you right now.”  Police called for backup due to his combative demeanor, booking him into Clayton County Jail for misdemeanor public drunkenness. Poirier later posted on Instagram that he is “working on myself.”  #DustinPoirier #UFC #mma #conormcgregor #arrested
