FLAGSTAFF, Ariz. (AP) -- Authorities say five Flagstaff police officers were injured trying to break up a fight between two groups outside San Felipe's Cantina.
Police say two of the officers had to be taken to Flagstaff Medical Center for treatment while the other three officers were treated at the scene for minor injuries.
Police say the officers responded to reports of a fight about 2 a.m. Thursday. They say the officers were assaulted when they tried to intervene.
Four men have been arrested in the case.
Police say 23-year-old William James Butler III, 24-year-old Isaiah Lewis Buck, 21-year-old Kenneth Brashawn Chapple and 22-year-old Brandon Lavon Chapple all are being held on suspicion of aggravated assault against police officers, disorderly conduct and resisting arrest.
Police didn't immediately know Friday whether the suspects had lawyers yet.
