Seven people wounded after gunfire erupts at Riverside nightclub during Halloween party

Seven people were wounded early Monday in a shooting during a Halloween party at a crowded nightclub in Riverside.

The shooting, which was reported to Riverside police shortly after midnight, happened inside and outside Sevilla Nightclub at 3252 Mission Inn Ave. during a Halloween-themed event and concert called “The Purge.”

Police said that when officers arrived at the club, they found two people suffering from gunshot wounds. They were taken by ambulance to a hospital for treatment. Five other people also wounded in the shooting arrived at local hospitals later to receive treatment. None of the gunshot wounds were life-threatening, said Sgt. Jayson Wood.

It is not clear what prompted the shooting, but Wood said it didn’t appear to be an active-shooter situation in which a gunman opens fire into a crowd. Gang investigators are looking into whether the shooting started following an altercation between two groups inside the club.

Detectives are interviewing witnesses and are hoping to access surveillance video from inside the club in an effort to piece together what happened. Many of the event attendees were in costume, which is making it difficult for authorities to get a description of a suspect, Wood said.

No one has been arrested in connection with the incident.

Anyone with information is asked to contact Det. Trevor Childers at (951) 353-7130 or Det. Karla Corbett at (951) 353-7134.
