TEMPE, AZ - Thirteen people were wounded in a shooting at a Tempe, Arizona, nightclub during a rap concert, police said on Saturday.
Tempe Police spokesman Sergeant Steve Carbajal said officers responded to reports of shots fired at the Clubhouse Music Venue at 11:30 p.m. Friday local time.
Carbajal said police had identified 13 victims from the incident. Two were in serious condition at local hospitals.
"Witnesses have reported that after the shooting, two black males wearing dark colored clothing fled the scene on foot," Carbajal said. "Those individuals have not been located at this time."
Rapper Nippsy Hustle was scheduled to appear at the club, according to the venue's web site. Local television news reported that gunfire erupted outside the club shortly before Hustle took to the stage.
Cellphone video of the shooting aftermath taken by a concert goer showed a man taking off his t-shirt to use as a tourniquet on a shooting victim.
Early Saturday, uniformed police had the crime scene at a strip mall sealed off behind yellow tape as plainclothes detectives continued their investigation.
A debris field spread across the parking lot indicated panic as a curbside party broke up outside the club. Plastic cups and other trash littered the area by the entrance, with empty tequila and cognac bottles tossed in the parking lot.
Police urged anyone with information about the incident to call Tempe police department's Silent Witness line: 480-WITNESS.
Tempe is in the east of the sprawling Phoenix valley.
