Three people have been killed and four others injured in a shooting at the Gable House Bowl in the U.S. coastal city of Torrance near Los Angeles, the Torrance Police Department said Saturday.

"Three men were pronounced dead at the scene and two others were taken to a hospital for treatment of their injuries," Sgt. Ronald Harris of the Torrance Police Department was quoted as saying by the local news outlet City News Service. Two other men sought medical attention on their own, Harris added.

Torrance police said they were still working to identify the suspected shooter or shooters.

Earlier, they tweeted there were reports of a shooting with "multiple victims down" and urged people to stay away from the area.

Several people on the scene told local media that there was a fight before the incident late Friday. One man said he heard "nine gunshots," the Los Angeles Times reported.

Gable House Bowl described itself as "the premier destination for bowling in the South Bay" on its website, adding that it has "games that both kids and adults will enjoy."

Torrance is located about 30 km southeast of downtown Los Angeles.
