At least seven people were injured in an overnight shooting at a California nightclub, according to police.
Police responded to a shooting at the Sevilla Nightclub in Riverside shortly after midnight where a caller reported shots being fired inside and outside the club.
The shooting took place during a Halloween event called "The First Purge."
What are the details?
Police responded to the 911 call at 12:04 a.m. where they found two victims at the scene, police said in a news release. They were transported by paramedics to a hospital.
A witness who didn't want to be identified told KTLA-TV that everyone was dancing when the shooting started.
"People started falling to the ground, and I thought people were fighting or dancing at first,” one witness told reporters, KTLA reported. “And I turn around, and then people started shooting and then I ran behind the bar … and then all of sudden there was a whole bunch of people crunched up by the exit.
"And I said, 'Why isn't anybody running?' ... then there was just shooting and I heard automatic gunshots. There was like 10 in a row ... I was just praying like 'God get me through this," he said.
The motive for the shooting is still unclear, but investigators believe it may have been the result of an altercation inside the club.
It appeared that several people may have been involved in the gunfire, Officer Ryan Railsback told reporters, according to KTLA.
Five other shooting victims arrived on their own to local hospitals for treatment. None of their injuries are believed to be life-threatening, Railsback said.
Two more suffered minor injuries during the incident, but they were not hospitalized.
The investigation is ongoing and the identities of the people involved in the shooting are not yet known.
