LOS ANGELES, June 14 (Xinhua) -- One person was killed and three others injured in a shooting incident at a Costco store in the city of Corona, 75 km east of downtown Los Angeles, local CBS news channel reported Friday night.
Witnesses told CBS that the fatal shooting occurred after an altercation between a white man and a lady with her child inside the membership-only warehouse, where seven to eight gunshots were heard.
Police from the city and Riverside county were swarming the area and the Costco was evacuated.
Corona police confirmed the incident was "stabilized" at 9:09 p.m. (0409 GMT Saturday), but did not disclose when the gunfire broke out, what led up to it, how many people were hurt and whether anyone was in custody.
"There is no apparent threat to our community from any outstanding persons. We will release more information as we work to confirm the facts," the Corona Police Department tweeted.
Many witnesses said that there was chaos at the scene since shoppers were trying to escape through the store's emergency doors after hearing gunshots but the doors were locked.
"It's not very fun when you're scared and you're running for your life, and you're trying to open a door that says 'emergency' and they don't open," Navi, a shopper, told local KTLA news channel. "Everybody was freaking out. People were falling over each other."
"Everybody's running around," she said. "It's scary."
