TEMPE, Arizona --
Police made one arrest and were looking for two other suspects after a shootout amid a large crowd outside an Arizona nightclub left 14 people wounded and set off a chaotic scene as the injured screamed for help and hundreds tried to flee.
The number of people confirmed to have been wounded in the late-Friday shooting in the Phoenix suburb of Tempe rose to 14 after a person went to a hospital Saturday with a gunshot wound to the foot, police spokesman Lt. Mike Horn said.
None of the wounded had life-threatening injuries. Twelve of them had relatively minor injuries, some driving themselves to local hospitals, while two were seriously hurt.
"People were running in all different directions, and some people were trying to force their way into the bar to get away," Horn said. "It was incredibly chaotic, and understandably so. Again, we're just fortunate that no one was killed."
The man in custody is one of three who opened fire at one another after they began arguing as a crowd of at least 250 people lined up outside The Clubhouse Music Venue for a hip-hop show late Friday, Horn said. He was in a car that a patrol officer stopped just after the shooting.
Horn said all three men are believed to be affiliated with Phoenix-area gangs. He asked for the public's help in identifying the two still at large.
Witness Paul Butler was among the crowd waiting to get into the club late Friday to hear Los Angeles rapper Nipsey Hussle perform. Butler told KTVK-TV that he heard a series of pops as the gunfire erupted.
"And you see everybody running, couple more shots, everybody running," Butler told the station. "It was pure chaos."
Police had only a vague description of suspects wearing dark clothing who ran away from the club on East Broadway Road, about seven miles (11 kilometers) east of downtown Phoenix.
Hussle never took the stage for the midnight show but tweeted after the shooting: "Az .... y'all gotta be cool man. This ... ain't rite."
A phone call and email to his publicist weren't immediately returned.
The website for the club - located in a strip mall within two miles (three kilometers) of Arizona State University's main campus in Tempe - says it's been in operation for six years hosting music shows nightly for all age groups.
Horn said the one suspect in custody was being held on 13 counts of aggravated assault and one count of assisting a criminal street gang.
