A security guard claimed Jon Jones' fiancée was bleeding from the nose and mouth -- and was scared to return to the hotel room where the UFC champ was staying -- in a 911 call before his arrest.
"We've got a possible DV call. Domestic violence call. Female is bleeding from the nose and mouth," a Caesars Palace security official told Las Vegas Metro PD dispatch around 4:30 AM on September 24.
Security almost immediately informs dispatch the male suspected of being involved in the incident is "professional MMA fighter, Jonathan Jones."
FYI, Jones was in Vegas because his epic 2013 fight against Alexander Gustafsson was inducted into the Hall of Fame.
