They arrived to find people “screaming” outside a ballroom dance studio, reportedly the Star Dance Studio on Garvey Avenue, and several victims still inside.
Videos posted online showed officers swarming the area, firefighters attending to injured people and victims on stretchers being put into ambulances.
Seafood restaurant owner Seung Won Choi told the LA Times that three people rushed into his business and told him to lock the door because a man with a machine gun and multiple rounds of ammunition was outside.

“The suspect, fled the scene and remains outstanding.”
In an earlier update, police had said nine people were killed.
Captain Meyer also confirmed investigators are looking into another incident at a second dance studio nearby and “trying to determine if there is a connection”.
The local community has been urged to remain vigilant while officers hunt for the suspect and try to establish a motive for the attack.
‘Home to one of the largest Asian communities’
In a tweet, City Controller Kenneth Mejia, who is an official in the government of Los Angeles, said his “heart goes out to those who lost loved ones tonight” in the “mass shooting”.
“Monterey Park is home to one of the largest Asian communities in Los Angeles County, and many were out celebrating the Lunar New Year,” he added.
Tens of thousands of people had gathered on Saturday afternoon for a two-day festival, which is considered one of the largest in the region.
Earlier in the day, crowds were able to enjoy various activities, watch live entertainment and visit “hundreds of vendors” as part of the celebrations, according to a notice by the City of Monterey Park.
