Gunfire broke out in a crowd waiting outside a Tempe, Arizona club where rapper Nipsey Hussle was due to perform on Friday night.
The shooting happened just before midnight in the parking lot of the Clubhouse Music Venue. Tempe police sergeant Steve Carbajal told the Associated Press that "some sort of altercation" arose in the crowd, and that the police were seeking two suspects, both young men, who fled the scene after the shooting.
At least 13 people were injured, and two have been hospitalized in serious condition.
Los Angeles-based Nipsey Hussle, who was headlining the Clubhouse show, did not end up taking the stage on Friday night. He later tweeted:
"Az....y'all gotta be cool man. This shit ain't rite."
According to the Phoenix New Times, a stabbing had occurred at the same venue’s parking lot in 2009.
