The gunfire was reported around 10:22 p.m. local time inside a Chinese-owned ballroom dance studio on West Garvey Avenue in Monterey Park.
Source npr.org, Local police arrived to find “individuals pouring out of the location,” LA County Sheriff’s Department’s Captain Andrew Meyer said in a news conference on Sunday early morning.
At least 10 people were taken to area hospitals with conditions ranging from stable to critical.
Local authorities are looking for a man who fled after the shooting. Police are also investigating a possible second scene in Alhambra, about two miles north of Monterey Park.
Meyer did not give further details about the shooter or possible motive. He added that it was unclear whether the shooting was a targeted hate crime.
The FBI and state authorities are also involved in the investigation.
Over 59,000 people live in Monterey Park, 65 percent of whom identify as Asian, according to the Census Bureau.
The attack occurred at the end of the first day of a two-day street festival to celebrate Lunar New Year. The event, which began on the eve of Lunar New Year, is one of the largest free street fairs in Southern California, typically drawing crowds of over 100,000 visitors and over a hundred food vendors, performances and merchants.
Monterey Park Police said the festival has been canceled because of the shooting.
